3D HOLOGRAM FAN
What is Hologram? Well to be precise, hologram is a 3D projection that exists freely in space and is visible to everyone without a need for any 3D equipment.
Now let’s come down to 3D hologram fans. What are they? These are little devices to support our holography process. As India is moving towards being more digital in terms of all aspects, standing out and getting brand visibility is getting way too difficult.
The electric hologram fan is getting popular for its 3D holographic display
The device’s single blade spins in high speed, generates moving images
The trend could be noticed after a video of the futuristic model became viral on social media
Single blade device can produce 3D holographic animations. According to a report stated, the 3D hologram display was invented by Zhou Quan and few of his fellow graduates from the Southeast University in Nanjing, east China.
Animation of a shape-changing object and the installation of a mini engine were created after the hand-held fan started spinning.
Holograms are those shiny, metallic patterns with ghostly images floating inside them that help to defeat counterfeiters: they're very hard to reproduce so they help to stop people printing illicit copies of banknotes. Credit cards usually have holograms on them too and software packages also frequently have hologrammatic seals to prove their authenticity.
Holograms are sort of "photographic ghosts": they look like three-dimensional photos that have somehow got trapped inside glass, plastic, or metal. When you tilt a credit-card hologram, you see an image of something like a bird moving "inside" the card. What makes it different from an ordinary photograph?
Suppose you want to take a photograph of an apple. You hold a camera in front of it and, when you press the shutter button to take your picture, the camera lens opens briefly and let’s light through to hit the film. All the light travelling from the apple comes from a single direction and enters a single lens, so the camera can record only a two-dimensional pattern of light, dark, and colour.
The motors used in the fan are same as the one used in drones.
The battery can last longer and withstand the power of the high spinning speed of LED screen in order to create a 3D hologram.
3D hologram fan display, 3D effect image and video are produced by rotating led fans. It can help shop owners spread and share advertising content efficiently. It is a cost-effective solution to show a holographic fan effect floating free in the air.
THE INVENTION OF HOLOGRAM
Holograms were invented by a brilliant Hungarian-born physicist named Dennis Gabor (1900–1979) while he was working in the UK. He'd been researching optical physics in the 1940s, and carried out his breakthrough work in holography in the early 1950s. The remarkable thing about his invention is that it was many years ahead of its time: lasers, which made holography practical, did not appear until the 1960s. As Gabor's many patents show, he was a prolific inventor with wide-ranging interests across many different areas of physics. In the 1930s, he invented new kinds of electron multipliers and cathode-ray tubes; in the 1940s, he was experimenting with photography and projection, which set him on the road toward holography; later inventions included composite fabrics for use in television equipment, and various innovations in recording and transmitting sound.
HOW IT WORKS?
Laser light is much purer than the ordinary light in a flashlight beam. In a flashlight beam, all the light waves are random and jumbled up. Light in a flashlight beam runs along any old how, like schoolchildren racing down a corridor when the bell goes for home time. But in a laser, the light waves are coherent.
When a laser beam is split up to make a hologram, the light waves in the two parts of the beam are travelling in identical ways. When they recombine in the photographic plate, the object beam has travelled via a slightly different path and its light rays have been disturbed by reflecting off the outer surface of the object. Since the beams were originally joined together and perfectly in step, recombining the beams shows how the light rays in the object beam have been changed compared to the reference beam. In other words, by joining the two beams back together and comparing them, you can see how the object changes light rays falling onto it—and that's simply another way of saying "what the object looks like." This information is burned permanently into the photographic plate by the laser beams. So a hologram is effectively a permanent record of what something looks like seen from any angle.
Now this is the clever part. Every point in a hologram catches light waves that travel from every point in the object. That means wherever you look at a hologram you see exactly how light would have arrived at that point if you'd been looking at the real object. So, as you move your head around, the holographic image appears to change just as the image of a real object changes. And that's why holograms appear to be three-dimensional. Also, and this is really neat, if you break a hologram into tiny pieces, you can still see the entire object in any of the pieces: smash a glass hologram of a cup into bits and you can still see the entire cup in any of the bits.
PRICE?
The hologram fan price actually depends on the requirement. There are multi feature fans and there are fans with limited features. The price usually fluctuates as per demand and type of hologram an individual or group wishes to make use of.
HOLOGRAM FAN INDIA: A CRUCIAL LEAD
As India is one of the leading countries in technology, holographic fan in an era like this would make an intense difference in raising the levers of success much higher.
INSTRUCTIONS ON MAKING A HOLOGRAM
You make a hologram by reflecting a laser beam off the object you want to capture. In fact, you split the laser beam into two separate halves by shining it through a half-mirror (a piece of glass coated with a thin layer of silver so half the laser light is reflected and half passes through—sometimes called a semi-silvered mirror). One half of the beam bounces off a mirror, hits the object, and reflects onto the photographic plate inside which the hologram will be created. This is called the object beam. The other half of the beam bounces off another mirror and hits the same photographic plate. This is called the reference beam. A hologram forms where the two beams meet up in the plate.
ITEMS REQUIRED TO MAKE ONE
• A suitable object or set of objects
• Part of the laser beam to be directed so that it illuminates the object (the object beam) and another part so that it illuminates the recording medium directly (the reference beam), enabling the reference beam and the light which is scattered from the object onto the recording medium to form an interference pattern
• A recording medium which converts this interference pattern into an optical element which modifies either the amplitude or the phase of an incident light beam according to the intensity of the interference pattern.
• A laser beam that produces coherent light with one wavelength.
• An environment which provides sufficient mechanical and thermal stability that the interference pattern is stable during the time in which the interference pattern is recorded.

HOLOGRAM FAN DISPLAY VS PHOTOGRAPHY
Holography may be better understood via an examination of its differences from ordinary photography:
• A hologram represents a recording of information regarding the light that came from the original scene as scattered in a range of directions rather than from only one direction, as in a photograph. This allows the scene to be viewed from a range of different angles, as if it were still present.
• A photograph can be recorded using normal light sources (sunlight or electric lighting) whereas a laser is required to record a hologram.
• A lens is required in photography to record the image, whereas in holography, the light from the object is scattered directly onto the recording medium.
• A photograph can be viewed in a wide range of lighting conditions, whereas holograms can only be viewed with very specific forms of illumination.
• A photograph is a two-dimensional representation that can only reproduce a rudimentary three-dimensional effect, whereas the reproduced viewing range of a hologram adds many more depth perception cues that were present in the original scene.
TYPES OF HOLOGRAMS
Reflection Hologram
The reflection hologram, in which a truly three-dimensional image is seen near its surface, is the most common type shown in galleries. The hologram is illuminated by a “spot” of white incandescent light, held at a specific angle and distance and located on the viewer’s side of the hologram. Thus, the image consists of light reflected by the hologram. Recently, these holograms have been made and displayed in colour—their images optically indistinguishable from the original objects. If a mirror is the object, the holographic image of the mirror reflects white light; if a diamond is the object, the holographic image of the diamond is seen to "sparkle."
Although mass-produced holograms such as the eagle on the VISA card are viewed with reflected light, they are actually transmission holograms "mirrorized" with a layer of aluminium on the back.
Transmission Hologram
The typical transmission hologram is viewed with laser light, usually of the same type used to make the recording. This light is directed from behind the hologram and the image is transmitted to the observer’s side. The virtual image can be very sharp and deep. For example, through a small hologram, a full-size room with people in it can be seen as if the hologram were a window. If this hologram is broken into small pieces (to be less wasteful, the hologram can be covered by a piece of paper with a hole in it), one can still see the entire scene through each piece. Depending on the location of the piece (hole), a different perspective is observed. Furthermore, if an undiverged laser beam is directed backward (relative to the direction of the reference beam) through the hologram, a real image can be projected onto a screen located at the original position of the object.
Hybrid Hologram
Between the reflection and transmission types of holograms, many variations can be made.
Embossed holograms
To mass produce holograms for authenticity applications such as security hologram stickers or the holograms you find on credit cards, currency and passports, a two-dimensional interference pattern is pressed onto thin plastic foils. The original hologram is usually recorded on a photosensitive material called photo resist. When developed, the hologram consists of grooves on the surface. A layer of nickel is deposited on this hologram and then peeled off, resulting in a metallic “shim.” More secondary shims can be produced from the first one. The shim is placed on a roller. Under high temperature and pressure, the shim presses (embosses) the hologram onto a roll of composite material similar to Mylar. Embossed holograms are actually a combination many types of holograms.
Integral holograms
A transmission or reflection hologram can be made from a series of photographs (usually transparencies) of an object—which can be a live person, an outdoor scene, a computer graphic, or an X-ray picture. Usually, the object is “scanned” by a camera, thus recording many discrete views. Each view is shown on an LCD screen illuminated with laser light and is used as the object beam to record a hologram on a narrow vertical strip of holographic plate (holoplate). The next view is similarly recorded on an adjacent strip, until all the views are recorded. When viewing the finished composite hologram, the left and right eyes see images from different narrow holograms; thus, a stereoscopic image is observed. Recently, video cameras have been used for the original recording, which allows images to be manipulated through the use of computer software.
Holographic interferometry
Microscopic changes on an object can be quantitatively measured by making two exposures on a changing object. The two images interfere with each other and fringes can be seen on the object that reveals the vector displacement. In real-time holographic interferometry, the virtual image of the object is compared directly with the real object. Even invisible objects, such as heat or shock waves, can be rendered visible. There are countless engineering applications in this field of holometry.
Multichannel holograms
With changes in the angle of the viewing light on the same hologram, completely different scenes can be observed. This concept has enormous potential for massive computer memories.
Computer-generated holograms
The mathematics of holography is now well understood. Essentially, there are three basic elements in holography: the light source, the hologram, and the image. If any two of the elements are predetermined, the third can be computed. For example, if we know that we have a parallel beam of light of certain wavelength and we have a "double-slit" system (a simple "hologram"), we can calculate the diffraction pattern. Also, knowing the diffraction pattern and the details of the double-slit system, we can calculate the wavelength of the light. Therefore, we can dream up any pattern we want to see. After we decide what wavelength we will use for observation, the hologram can be designed by a computer. This computer-generated holography (CGH) has become a sub-branch that is growing rapidly. For example, CGH is used to make holographic optical elements (HOE) for scanning, splitting, focusing, and, in general, controlling laser light in many optical devices such as a common CD player.
WHY 3D HOLOGRAMS ARE SO FASCINATING?
3D holograms are new, innovative and most people have only seen them in Hollywood films. Now they have become reality in a particularly impressive way. The discrepancy between what the eyes see and what the mind is aware of can create an unusually long attention span, which is a great way of embedding product information in people’s minds or creating a good image. Although the eye sees what appears to be a real object or effect, such as fire, for example, the brain knows that what it is seeing cannot be real. And it is exactly this effect that automatically generates a long attention span in the observer, resulting in a 2–3-minute hologram being watched from beginning to end by up to 80% of people – an effect that cannot be achieved with a conventional film displayed on a screen.
Quite apart from that, a 3D hologram is highly appealing and therefore excellently suitable not only for presenting complex technical concepts, it is also virtually predestined for displaying precious stones and similar visually appealing goods. This technology makes it possible to additionally emphasize their beauty and perfection and to display them in an extremely aesthetic way, already making the presentation a sensual experience in itself.

HOW DO 3D HOLOGRAM FANS WORK?
Holographic projectors use holograms rather than graphic images to produce projected pictures. They shine special white light or laser light onto or through holograms. The projected light produces bright two- or three-dimensional images. While plain daylight lets you see some simple holograms, true 3-D images require laser-based holographic projectors. You can view such images from different angles and see them in true perspective. Miniature versions of such projectors are in development. Using such a projector, a Smartphone could create an image for the viewer in an empty space rather than on a small screen.
Holograms are sort of "photographic ghosts": they look like three-dimensional photos that have somehow got trapped inside glass, plastic, or metal. When you tilt a credit-card hologram, you see an image of something like a bird moving "inside" the card. What makes it different from an ordinary photograph?
Suppose you want to take a photograph of an apple. You hold a camera in front of it and, when you press the shutter button to take your picture, the camera lens opens briefly and let’s light through to hit the film. All the light travelling from the apple comes from a single direction and enters a single lens, so the camera can record only a two-dimensional pattern of light, dark, and colour.
The motors used in the fan are same as the one used in drones.
Holograms
The key to the operation of holographic projectors is the hologram. Before the advent of digital imaging, holograms were patterns on film. The photographer took a single source of light and split it into two. Half illuminated the subject and half went directly to the film, creating an interference pattern with the light reflected from the subject. A holographic projector used a similar light and the film to recreate an image of the subject.
Imaging
By 2004, digital displays were able to create such interference patterns and take the place of the hologram on film. This meant that companies could start work on projecting videos on holographic projectors. The projector shines lasers or pure white light through a digital display that is programmed with interference patterns corresponding to a series of images. The process creates an image in front of the projector by passing the light through the interference pattern.
Projection
In traditional projectors, light passes through a graphical image that blocks some of the light to create shading, and lets only some colours through to colour the projected picture. Holographic projectors generate the projected image by refraction through the interference pattern, losing hardly any light, and operating much more efficiently. They can be very small and generate very little heat. This makes them ideal for eventual applications in mobile electronic devices, for which power and space are limited.
Colour
A hologram or a digital holographic interference pattern works only with one colour, since the interference pattern comes from the interference from a single wavelength of light. To obtain colour, holographic projectors have to use coloured lasers that illuminate the corresponding interference patterns for their colours. As of January 2012 such holographic projectors are in the development stage.
True 3-D
A simple holographic projector with a light source shining through a flat interference pattern can produce an image that has three-dimensional qualities, but it is still flat. To create a true 3-D image, a holographic projector can use a spinning mirror to reflect the image to the observer. The mirror sends an image corresponding to the angle from which the observer is viewing the subject. As the observer moves around the subject he views it in different perspectives, and sees a three-dimensional image floating in space.

HOLOGRAM FAN DISPLAY VS PHOTOGRAPHY
Holography may be better understood via an examination of its differences from ordinary photography:
• A hologram represents a recording of information regarding the light that came from the original scene as scattered in a range of directions rather than from only one direction, as in a photograph. This allows the scene to be viewed from a range of different angles, as if it were still present.
• A photograph can be recorded using normal light sources (sunlight or electric lighting) whereas a laser is required to record a hologram.
• A lens is required in photography to record the image, whereas in holography, the light from the object is scattered directly onto the recording medium.
• A photograph can be viewed in a wide range of lighting conditions, whereas holograms can only be viewed with very specific forms of illumination.
• A photograph is a two-dimensional representation that can only reproduce a rudimentary three-dimensional effect, whereas the reproduced viewing range of a hologram adds many more depth perception cues that were present in the original scene.
TYPES OF HOLOGRAMS
Reflection Hologram
The reflection hologram, in which a truly three-dimensional image is seen near its surface, is the most common type shown in galleries. The hologram is illuminated by a “spot” of white incandescent light, held at a specific angle and distance and located on the viewer’s side of the hologram. Thus, the image consists of light reflected by the hologram. Recently, these holograms have been made and displayed in colour—their images optically indistinguishable from the original objects. If a mirror is the object, the holographic image of the mirror reflects white light; if a diamond is the object, the holographic image of the diamond is seen to "sparkle."
Although mass-produced holograms such as the eagle on the VISA card are viewed with reflected light, they are actually transmission holograms "mirrorized" with a layer of aluminium on the back.
Transmission Hologram
The typical transmission hologram is viewed with laser light, usually of the same type used to make the recording. This light is directed from behind the hologram and the image is transmitted to the observer’s side. The virtual image can be very sharp and deep. For example, through a small hologram, a full-size room with people in it can be seen as if the hologram were a window. If this hologram is broken into small pieces (to be less wasteful, the hologram can be covered by a piece of paper with a hole in it), one can still see the entire scene through each piece. Depending on the location of the piece (hole), a different perspective is observed. Furthermore, if an undiverged laser beam is directed backward (relative to the direction of the reference beam) through the hologram, a real image can be projected onto a screen located at the original position of the object.
Hybrid Hologram
Between the reflection and transmission types of holograms, many variations can be made.
Embossed holograms
To mass produce holograms for authenticity applications such as security hologram stickers or the holograms you find on credit cards, currency and passports, a two-dimensional interference pattern is pressed onto thin plastic foils. The original hologram is usually recorded on a photosensitive material called photo resist. When developed, the hologram consists of grooves on the surface. A layer of nickel is deposited on this hologram and then peeled off, resulting in a metallic “shim.” More secondary shims can be produced from the first one. The shim is placed on a roller. Under high temperature and pressure, the shim presses (embosses) the hologram onto a roll of composite material similar to Mylar. Embossed holograms are actually a combination many types of holograms.
Integral holograms
A transmission or reflection hologram can be made from a series of photographs (usually transparencies) of an object—which can be a live person, an outdoor scene, a computer graphic, or an X-ray picture. Usually, the object is “scanned” by a camera, thus recording many discrete views. Each view is shown on an LCD screen illuminated with laser light and is used as the object beam to record a hologram on a narrow vertical strip of holographic plate (holoplate). The next view is similarly recorded on an adjacent strip, until all the views are recorded. When viewing the finished composite hologram, the left and right eyes see images from different narrow holograms; thus, a stereoscopic image is observed. Recently, video cameras have been used for the original recording, which allows images to be manipulated through the use of computer software.
Holographic interferometry
Microscopic changes on an object can be quantitatively measured by making two exposures on a changing object. The two images interfere with each other and fringes can be seen on the object that reveals the vector displacement. In real-time holographic interferometry, the virtual image of the object is compared directly with the real object. Even invisible objects, such as heat or shock waves, can be rendered visible. There are countless engineering applications in this field of holometry.
Multichannel holograms
With changes in the angle of the viewing light on the same hologram, completely different scenes can be observed. This concept has enormous potential for massive computer memories.
Computer-generated holograms
The mathematics of holography is now well understood. Essentially, there are three basic elements in holography: the light source, the hologram, and the image. If any two of the elements are predetermined, the third can be computed. For example, if we know that we have a parallel beam of light of certain wavelength and we have a "double-slit" system (a simple "hologram"), we can calculate the diffraction pattern. Also, knowing the diffraction pattern and the details of the double-slit system, we can calculate the wavelength of the light. Therefore, we can dream up any pattern we want to see. After we decide what wavelength we will use for observation, the hologram can be designed by a computer. This computer-generated holography (CGH) has become a sub-branch that is growing rapidly. For example, CGH is used to make holographic optical elements (HOE) for scanning, splitting, focusing, and, in general, controlling laser light in many optical devices such as a common CD player.
WHY 3D HOLOGRAMS ARE SO FASCINATING?
3D holograms are new, innovative and most people have only seen them in Hollywood films. Now they have become reality in a particularly impressive way. The discrepancy between what the eyes see and what the mind is aware of can create an unusually long attention span, which is a great way of embedding product information in people’s minds or creating a good image. Although the eye sees what appears to be a real object or effect, such as fire, for example, the brain knows that what it is seeing cannot be real. And it is exactly this effect that automatically generates a long attention span in the observer, resulting in a 2–3-minute hologram being watched from beginning to end by up to 80% of people – an effect that cannot be achieved with a conventional film displayed on a screen.
Quite apart from that, a 3D hologram is highly appealing and therefore excellently suitable not only for presenting complex technical concepts, it is also virtually predestined for displaying precious stones and similar visually appealing goods. This technology makes it possible to additionally emphasize their beauty and perfection and to display them in an extremely aesthetic way, already making the presentation a sensual experience in itself.

HOW DO 3D HOLOGRAM FANS WORK?
Holographic projectors use holograms rather than graphic images to produce projected pictures. They shine special white light or laser light onto or through holograms. The projected light produces bright two- or three-dimensional images. While plain daylight lets you see some simple holograms, true 3-D images require laser-based holographic projectors. You can view such images from different angles and see them in true perspective. Miniature versions of such projectors are in development. Using such a projector, a Smartphone could create an image for the viewer in an empty space rather than on a small screen.
Holograms are sort of "photographic ghosts": they look like three-dimensional photos that have somehow got trapped inside glass, plastic, or metal. When you tilt a credit-card hologram, you see an image of something like a bird moving "inside" the card. What makes it different from an ordinary photograph?
Suppose you want to take a photograph of an apple. You hold a camera in front of it and, when you press the shutter button to take your picture, the camera lens opens briefly and let’s light through to hit the film. All the light travelling from the apple comes from a single direction and enters a single lens, so the camera can record only a two-dimensional pattern of light, dark, and colour.
The motors used in the fan are same as the one used in drones.
Holograms
The key to the operation of holographic projectors is the hologram. Before the advent of digital imaging, holograms were patterns on film. The photographer took a single source of light and split it into two. Half illuminated the subject and half went directly to the film, creating an interference pattern with the light reflected from the subject. A holographic projector used a similar light and the film to recreate an image of the subject.
Imaging
By 2004, digital displays were able to create such interference patterns and take the place of the hologram on film. This meant that companies could start work on projecting videos on holographic projectors. The projector shines lasers or pure white light through a digital display that is programmed with interference patterns corresponding to a series of images. The process creates an image in front of the projector by passing the light through the interference pattern.
Projection
In traditional projectors, light passes through a graphical image that blocks some of the light to create shading, and lets only some colours through to colour the projected picture. Holographic projectors generate the projected image by refraction through the interference pattern, losing hardly any light, and operating much more efficiently. They can be very small and generate very little heat. This makes them ideal for eventual applications in mobile electronic devices, for which power and space are limited.
Colour
A hologram or a digital holographic interference pattern works only with one colour, since the interference pattern comes from the interference from a single wavelength of light. To obtain colour, holographic projectors have to use coloured lasers that illuminate the corresponding interference patterns for their colours. As of January 2012 such holographic projectors are in the development stage.
True 3-D
A simple holographic projector with a light source shining through a flat interference pattern can produce an image that has three-dimensional qualities, but it is still flat. To create a true 3-D image, a holographic projector can use a spinning mirror to reflect the image to the observer. The mirror sends an image corresponding to the angle from which the observer is viewing the subject. As the observer moves around the subject he views it in different perspectives, and sees a three-dimensional image floating in space.

As India is one of the leading countries in technology, holographic fan in an era like this would make an intense difference in raising the levers of success much higher.
INSTRUCTIONS ON MAKING A HOLOGRAM
You make a hologram by reflecting a laser beam off the object you want to capture. In fact, you split the laser beam into two separate halves by shining it through a half-mirror (a piece of glass coated with a thin layer of silver so half the laser light is reflected and half passes through—sometimes called a semi-silvered mirror). One half of the beam bounces off a mirror, hits the object, and reflects onto the photographic plate inside which the hologram will be created. This is called the object beam. The other half of the beam bounces off another mirror and hits the same photographic plate. This is called the reference beam. A hologram forms where the two beams meet up in the plate.
ITEMS REQUIRED TO MAKE ONE
• A suitable object or set of objects.
• Part of the laser beam to be directed so that it illuminates the object (the object beam) and another part so that it illuminates the recording medium directly (the reference beam), enabling the reference beam and the light which is scattered from the object onto the recording medium to form an interference pattern.
• A recording medium which converts this interference pattern into an optical element which modifies either the amplitude or the phase of an incident light beam according to the intensity of the interference pattern.
• A laser beam that produces coherent light with one wavelength.
• An environment which provides sufficient mechanical and thermal stability that the interference pattern is stable during the time in which the interference pattern is recorded.
