Abstract

Color information is recorded on a colorless substrate by having each color separation amplitude modulate a different spatial frequency carrier. This is accomplished in a single exposure using an appropriate color-encoding filter. The reconstruction of the color scene involves a point source projector with a color decoding mask. The light output of the projector, for sources of a given brightness, is shown to be proportional to the total number of lines in the encoding filter. The relatively, high efficiency of an encoded phase transparency is evaluated, and a decoding method is shown.
