Well to be precise, holographic 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.

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.
ABOUT 3D VISION FAN
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.

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.
