Abstract

Pseudo-coloring of a photograph in a coherent optical processing system can be achieved through the utiliza-tion of the newly advanced technique of halftone screens. The basic principle of the pseudo-coloring method is to mix the high diffraction order outputs of the halftone photograph generated by lasers of different wave-lengths in a coherent optical system. A discussion of the theory, the method, and its potential applications will be given.
