Abstract

A simple technique utilizing a white-light processing system for the pseudocolor encoding of photographic materials by density is presented. Pseudocolored output of many different color codes is obtained by selectively spatial filtering the dispersed colors of the various high-diffraction orders of a halftone input. Besides permitting a large variety of color codes, this white-light technique would also eliminate all coherent artifact noises that plague coherent systems. Experimental results are presented, and comparison with the coherent technique is provided.
