Embossed hologram motion pictures for television playback.
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.
