Abstract
Method and apparatus are described for producing a replica of a pattern composed of differently-colored zones, mutually exclusive areas of the replica being so encoded from zone to zone that when it is suitably illuminated, the light from each zone can be treated separately from the light from each of the other zones. Apparatus is also described for reconstructing from such separately treated light an image of the original pattern in which each zone may be given an arbitrary hue and intensity. The 'color' of any one zone in such image can be black or white, as well as gray.
