Embossed hologram motion pictures for television playback.

Abstract

Techniques for recording, replicating, and reconstructing relief phase holograms are described. Replication is accomplished by embossing the relief pattern into transparent plastic using a metal master prepared by plating holograms exposed in photoresist. Image noise is reduced, without producing speckle patterns, by redundant recording. A motion picture, in the form of a sequence of Fraunhofer holograms embossed into a plastic tape, can be played out very simply because of the image immobilization of that type of hologram.
