Method and apparatus for producing full color stereographic holograms

Claim 1

An apparatus for photographically recording temporally coherent images of multiple views of a subject for use in producing a stereographically correct, temporally coherent hologram, comprising: a multiple lens exposure system having a plurality of lenses, each said lens having a shutter associated therewith, means for triggering each of said shutters, said lenses being disposed relative to the subject so that said lenses all face a front side and are trained in the general direction of the subject; each of said lenses being disposed in a specific spaced relationship relative to the adjacent lenses in a stereographic linear arrangement to approximate the stereoscopic view from the eyes of an individual observing the subject from the location of the respective lenses; and means for triggering said shutters to obtain multiple, temporally coherent exposures of the subject, so that when such exposures ar placed side-by-side in a linear arrangement corresponding to the relative positioning of said lenses, and are sequentially projected within a holographic optical printer wherein a light sensitive holographic plate is positioned to be exposed to an interference pattern created by the interference of a reference beam and an object beam thereupon, the object beam being directed upon and through said multiple coherent exposures in sequence, the reference beam being coherent to said object beam, so that a temporally coherent, stereographically correct image of the subject is obtained, the spacing of said lenses being designed so that said multiple coherent exposures have a spacing corresponding to a desired spacing of images projected upon the holographic plate.
