Holography

Holography is a technology that makes it possible to record and then rebuild light scattered from an item, giving the impression that the object is in the same position with respect to the recording medium as when it was first recorded. The recorded picture hologram appears three-dimensional because the viewing system's position and orientation alter the image in precisely the same way as if the object were still there. "Holography is a technique that allows a wavefront to be recorded and later reconstructed. This captures the phases as well as the amplitude of light received from various 3D object components. This is predicated on the interference phenomena. Hungarian physicist Dennis Gabor made the discovery of holograms in 1947; for this accomplishment, he was awarded the 1971 Nobel Prize in Physics. It was made feasible by other scientists' ground breaking work in the realm of physics.
