Holographic readout system

Claim 1

A multicolor display system, comprising a viewing screen having a multiplicity of closely spaced photoluminescent segments thereon in a regular array of alternating red, blue and green segments, a hologram positioned relative to said screen to project an image thereon of a multicolor subject when the hologram is illuminated by a readout beam of coherent light, wherein said hologram has been produced by recording the interaction of a reference beam and an object beam passed through an encoded black and white transparency, said transparency having a regular array of alternating first, second, and third sections which is geometrically similar to said regular array of alternating red, blue, and green segments, with all of said first sections, said second sections, and said third sections containing information in terms of transparency about only red, only blue, and only green respectively present in portions of a multicolor subject, and means for directing a readout beam of coherent light onto said hologram to reconstruct said image on said screen in a multicolor display.

Claim 10

A method of reproducing a full color image of information recorded on a black-and-white recording medium, which comprises: positioning a viewing screen bearing a multiplicity of closely spaced photoluminescent segments in an array of sequentially repetitive red, blue and green segments, in the readout plane of a hologram wherein said hologram has been produced by recording the interaction of a reference beam and the Fourier transform wavefront of an encoded black and white transparency having a regular array of alternating first, second, and third sections which is geometrically similar to said alternating red, blue, and green segments, with all of said first sections, said second sections, and said third sections containing information in terms of transparency about only red, only blue, and only green respectively present in portions of a multicolor subject, and directing a readout beam Of coherent light onto said hologram to reconstruct the image of said multicolor subject on said screen in a multi-color display.

Claim 11

A method of reproducing a full color image of information recorded on a black-and-white recording medium, which comprises: positioning a viewing screen bearing a multiplicity of closely spaced photoluminescent segments in an array of sequentially repetitive red, blue and green segments, in the readout plane of a hologram wherein said hologram has been produced by recording the interaction of a reference beam and the Fourier transform wavefront of an encoded black and white transparency having a regular array of alternating first, second, and third sections which is geometrically similar to said alternating red, blue, and green segments, with all of said first sections, said second sections, and said third sections containing information in terms of transparency about only red, only blue, and only green respectively present in portions of a multicolor subject, and directing a readout beam Of coherent light onto said hologram to reconstruct the image of said multicolor subject on said screen in a multi-color display.
