Gram Gram Hologram!
We all like to click photos. But most of all what we see in the image is 2- Dimensional. Have you imagined a 3- Dimensional photographic image!!?? Is it a reality or not?? Yes, I say, a reality. What is a Hologram? The 3-Dimensional image which I talked about earlier is possible through Hologram. Then, what is a Hologram? It uses light scattered from an object to form a 3-D image. What do we need for that? We need a source of light such as a Laser, projector laser, beam splitter, mirror, lenses (diverging lenses) the surface on which we are going to display it and of course the object itself!!!! And what else is remaining? Ohhhh!!! We forgot the Holographic film!!! Otherwise who is going to record light patterns coming from the target object??!! How Hologram works? It uses the principles and the concepts of light waves. Basically, there is a beam of light rays coming from a laser light source. Then, this beam gets split into two beams using the beam splitt
