Holography

Holography is a technique that allows the light from an object to be recorded and reconstructed so an image of the object will be seen even when the object is no longer present, thus making the image appear three-dimensional. The image changes as the position and orientation of the viewing system changes same way as if the object was still there.Holography was invented by the Hungarian-British physicist Dennis Gabor  in 1947 for which he received a Nobel Prize in Physics.
