Abstract A method and apparatus for constructing and relaying an optical holographic record containing a plurality of very small holograms, each of which contains color information independent of the other holograms. Each piece of full color information, such as a frame of an ordinary color photographic movie, is recorded as an individual hologram. The record is a narrow, elongated flexible film with the holograms formed in a line along its length, each hologram touching those on either side thereof. One or more light sensitive detectors for converting an image into a time varying electronic signal are positioned to receive holographically reconstructed signals and transform them into a form acceptable to an ordinary color television set for displaying the color information thereon. One, two and three image detecting tube systems are disclosed. Several independent monochromatic components of a color information signal are carried on a single optical-electronic channel by modulation onto carrier frequencies either optically or electronically prior to construction of the hologram record. In a preferred embodiment described, the hologram record is constructed in a manner to reconstruct a broad bandwidth luminance signal in a position spatially separated from the color component signal.
A holographic record, comprising an elongated flexible film record member having a plurality of individual holograms constructed along its length in a touching relationship, each of said holograms containing a distinct piece of full color information that may be reconstructed with a single monochromatic spatially coherent light beam in a manner to form two spatially separated monochromatic images, one image corresponding to a luminance component and the other image corresponding to a color component of said distinct piece of full color information.
