  • Patent number: 4427994
    Abstract: A Color Separator for a Map Display Video Generator utilizing a Fresnel lens to expand a multicolor light signal output from a point of light scanned map film to a stationary area that entirely fills an input end of a bundle of optical fibers the other end of which bundle is divided into three smaller bundles. The light output from each smaller bundle is first passed through a colored filter to thereby separate the light into the primary colors red, green and blue. The separated light is then converted to an electrical signal by photomultipliers and used to generate a color video signal applied to a color cathode ray tube display to display the map thereon.
