What is Hologram?


              Often you have seen a hologram made of their company on many things to prove their authenticity. In fact Holograms are similar to photographs that appear to be three-dimensional (3D). The hologram creates an image that can be viewed from multiple angles. When you look at a hologram, it looks like you are looking at an actual physical object, not seeing a picture. When you look at the image of the hologram you see that 3D, but the surface on which it is stored is flat. It is derived from the Greek words holos / holos (whole) and grama / gramma (message).

              The technique and science of making holograms is called Holography. Holography creates a hologram of an image using Light Beam and Laser. The theory of holography was developed by physicist Denis Gerber in 1947, and the development of laser technology made holography possible. For this, Dennis Gerber was also awarded the 1971 Nobel Prize in Physics. Subsequently it was put into industrial use. Its use was seen on book covers, credit cards etc. It looks like a three-dimensional image or a triangle, but it is basically a two-dimensional shape, which is why it is also called a 3D hologram. Today there has been a lot of development in this technology. Now its use is no longer limited to various products or credit cards. This technique is also widely used in films and visual performances. In this, you are shown the two-dimensional shape in the 3D image, which makes you feel that the object is in front of you.

How do holograms work?

               The actual hologram is created by dividing the ray of light. When a laser beam is split to form a hologram, the light waves of the beam are split into two (object beam and reference beam) and travel equally on both sides. When they recombine in the photographic plate, the object beam passes through a slightly different path and its light rays are distracted by reflecting off the outer surface of the object. And when these two beams join together, a three-dimensional image of the object appears.

               A 3D hologram displays products, objects, and animated scenes three-dimensional. Unlike the film displayed on a simple screen, the film shown in 3D hologram is visible from all angles. Its most interesting thing is that unlike 3D Television or Virtual Reality, a 3D hologram can also be viewed without 3D glasses, which is used in trade fairs, exhibitions and similar programs. Can prove to be quite profitable.

3D Hologram

To display 3D holograms, these things are usually required:

1. A hologram projector / Projector (also known as Holograph Pyramid / Holograph Pyramid or Holography Display / Holography Display), which makes holographic 3D projection possible.
2. A 3D hologram that is projected directly into the room and displays the object.

What is a 3D hologram used for?

               To present products in an innovative way: 3D hologram is a new innovative way of presenting products. In addition, holograms are not only useful for displaying three-dimensional objects, they are also able to make the scene real like fire, rain, fog or smoke. A common image also becomes a real attraction when presented as a 3D hologram.


               To create a world of emotions: 3D holograms display products in a completely unique way. For example a hologram is used to provide an object with a completely attractive and literary coordinated environment. No other technology has been able to equally present the benefits of a product such as 3D holograms. Observers see it as if they are talking directly and emotionally.

               To explain technically complex concepts in a simple way: 3D holograms are an ideal way of presenting complex materials in a illustrative, simple way. This process helps to delve into new and unknown aspects.
