Hologram

Many of us have a simple hologram in our possession. Small instances appear on credit cards, sports gear labels and magazine covers. Holograms are pictures recorded in 3D. And you don't require special glasses to see the 3D effect it produces.

The technology was invented in 1948 by Hungarian physicist Dennis Gabor, who later received a Nobel Prize for it. The majority of holograms are produced simply by bouncing a laserlight off an object, and onto a photographic plate. In brief, the plate records how the picture interferred with the laserlight. In all three dimensions. Along with added depth. Contrary to popular belief, lenticular technology is not the same as hologram technology.
