A method of producing a three-dimensional image of an object by recording on a photographic plate or film the pattern of interference formed by a split laser beam and then illuminating the pattern either with a laser or with ordinary light.
(General Physics) the science or practice of producing holograms
ho•log•ra•phy(həˈlɒg rə fi)
the process or technique of making holograms.
A method of making a three-dimensional image of an object by using a divided beam of light from a laser. The laser light is directed by mirrors so that one beam reflects off the object onto a photographic plate or film while the other beam is aimed directly at the plate or film. The two beams are combined to form a three-dimensional image of the object.
a technique for producing a three-dimensional photographic representation, recorded on film by a reflected laser beam of a subject illuminated by part of the same laser beam.See also: Photography
