  • n. A three-dimensional image of an object created by holography.

  • n. A photographic image giving the observer a seemingly three-dimensional view of the represented object. The three-dimensional effect is produced by exposing a photographic recording medium to an interference pattern generated by a coherent beam of light (as from a laser) reflected from the subject, interacting with a beam directly from the source. The full three-dimensional effect requires illumination of the image with coherent light, but less perfect three-dimensional visual effects may also be observed when the hologram is illuminated with white light.

Etymologies

holo- + -gram, from Ancient Greek ὅλος (holos, "whole") + γραμμή (gramme, "letter, line"), coined in 1964 by Hungarian-born British scientist Dennis Gabor, the 1971 Nobel prize winner in physics for his work in holography. (Wiktionary)
