Abstract
A plastic sheet is embossed with three angularly-multiplexed holograms to represent three colors of an image. Light is directed to the holograms from three directions, in sequence, to recreate the three colors of the image in sequence on the face of a black-and-white vidicon. The three field sequential signals from the vidicon are sequentially stored in three solid state frame memories, from which the three color-representing signals are read out simultaneously to the three guns of a color kinescope. Alternatively, the three holograms represent red, blue and luminance, and only red and blue frame memories are required, and during display the luminance-representing signal is repeatedly read out from the vidicon to the color kinescope simultaneously with repeated readout from the red and blue frame memories.
