摘要
In a motion picture record in which successive frames of a motion picture are manifested by a series of successive holograms, such as phase holograms, greater redundancy and a saving in record material are achieved by having each one of the holograms partially overlap both the hologram which immediately precedes and the hologram which immediately succeeds that hologram in the series. The problem of unwanted spatial beat frequencies, which results from such overlap and is dependent on the amount of such overlap, can be eliminated by restricting the amount of overlap to a value such that the minimum spatial beat frequency is less than the ultimate resolution of the playback system (e.g. closed circuit television) employed in reconstructing the motion picture from the motion picture record.
