Space-Invariant Holography with Quasi-Coherent Light

Abstract

Optical configurations for performing holography with light of limited coherence are analyzed. Such configurations, which may employ mirrors and gratings in preference to lenses and prisms, are space invariant in that the optical pathlength of a ray between object and hologram recording planes depends only on its initial direction, not on its location in the object plane. Holograms of arbitrary size made from object transparencies of arbitrary size and light of limited coherence.
