hologram

a photographic record produced by illuminating the object with coherent light (as from a laser) and, without using lenses, exposing a film to light reflected from this object and to a direct beam of coherent light. When interference patterns on the film are illuminated by the coherent light a three-dimensional image is produced

hologram

[′häl·ə‚gram]
(optics)
The special photographic plate used in holography; when this negative is developed and illuminated from behind by a coherent gas-laser beam, it produces a three-dimensional image in space. Also known as hologram interferometer.
