• noun
A three-dimensional image formed by the interference of light beams from a laser or other coherent light source.
"The science museum exhibit featured a remarkably lifelike hologram of an ancient artifact that visitors could walk around."
A physical photographic recording of a light field, rather than of an image formed by a lens, which is used to display a fully three-dimensional subject.
"To create a true hologram, the physics students carefully split the laser beam to capture the light's phase and amplitude on a specialized photographic plate."
Word Origin & Etymology
Coined in 1949 by Hungarian-British physicist Dennis Gabor, from the Greek words 'holos' (whole) and 'gramma' (message or drawing). The term reflects the technique's ability to record the entirety of a light wave's information, including both amplitude and phase.
