PARTIALLY OVERLAPPING HOLOGRAM MOTION PICTURE RECORD

1322206 Holography R C A CORPORATION 6 Nov 1970 [25 Nov 1969] 52904/70 Heading G2J A motion picture system comprises a record wherein successive holograms are recorded on a carrier 306 each of the same size and partially overlapping adjacent ones by a given amount, and wherein the reconstructed images which include spatial beat frequencies having a minimum value which depends on the overlap, means 506 for sequentially illuminating the holograms 500 is sequentially obtain reconstructed real images in a given area of space 512 of motion picture frames 304, and image responsive means 514- 518 including a wave sensitized surface coincident with the given area and having a given overall resolution, the amount of overlap and resolution being so related that the value of the minimum spatial beat frequency is not less than the ultimate resolution capability of the image responsive means. The hologram may be phase and Fraunhofer holograms. Redundancy and the minium spatial beat frequency are introduced through, for example a phase grating, 324 or a plurality of mirrors. In recording the hologram a synchronized drive operates carrier 306 and film 304 and a shutter 302. In reconstruction the tape carrier 500, which may be a pressing, is moved continuously past laser 506. The image responsive means may be a television camera.
