What is HOLOGRAM?

Answer 2

Well, a hologram is like a picture. Sort of. You see, when you look at a picture -- like a photograph -- it is flat. If you took a regular picture of a big marble, and it had a smaller marble behind it, you would not be able to look around the big marble to see the little one.

With a HOLOGRAM, you would be able to look around the big marble and see the little one behind it. It's true. That's because a hologram is in 3-D. The letter "D" in "3-D" stands for the word "dimension". The "3" in "3-D" stands for how many "dimensions" something has.

A photo, a piece of paper -- or even this computer screen -- is 2-D, or two dimensions: up and down (1) and left and right (2). When something has 3-D, like the world in which we live -- or a hologram -- it has an added dimension: up and down (1), left and right (2) and forwards and backwards (3). When talking about dimensions, we call forwards and backwards "depth". So . . . when we say that a hologram has 3 dimensions, it means we can see up and down, and left and right, just like a picture or photo . . . but we can also look "into" the hologram because the hologram, and the objects that it contains, has depth.

Looking at a certain types of holograms is just like looking at something that is really in front of your eyes. In fact, some holograms are so real that you want to take your hand and touch the object in it -- but your hand goes right through thin air. Imagine getting up to get a soda while you're watching a holographic Super Bowl. When you walk across your living room, you'd walk right through the players. You could try to kick the ball, but your foot would pass right through it.

Holography (from the Greek, Όλος-holos whole + γραφή-graphe writing) is the science of producing holograms; it is an advanced form of photography that allows an image to be recorded in three dimensions. The technique of holography can also be used to optically store, retrieve, and process information. It is common to confuse volumetric displays with holograms, particularly in science fiction works such as Star Trek, Star Wars, Red Dwarf, and Quantum Leap.

Answer 5

A hologram is a 3-dimentional image that can reflect different shades and colors when viewed from different angles. Many companies use their holograms on their products as a proof of genuineness of their product to avoid adultration or tempering in their products or to avoid cheaper variants.

Answer 7

noun: the intermediate photograph (or photographic record) that contains information for reproducing a three-dimensional image by holography
holography; noun: the branch of optics that deals with the use of coherent light from a laser in order to make a hologram that can then be used to create a three-dimensional image

Answer 8

hologram is a greek word which means that holo means whole and graphy means writing.
it is an advanced version of photography.
we can sat that holography is the 3D photography.

Answer 9

Hologram is made in such a way that when the object wave and incident wave is incident on a photographic plate a holographic image is formed...............

Answer 10

The pattern produced on a photosensitive medium that has been exposed by holography and then photographically developed.
