Paper Abstract

The Tepanism of photogrphio relief images of silver halide plate and its applications have been reported ' 1. In this paper we describe an interesting phase modulation phenomenon of the reflected light from the relief images and propose a new pseudocolor encoding technique with a white-light reflective processor. It consists of two main steps: 1) a grating encoded plate of a blaok,white image should be made by contact printing; 2) the pseudocolor image is obtained by placing the encoded plate at input plane and spatial filtering at Fourier plane in a reflective white-light processor. This technique offers the advantage that the colors of the output image vary with the incident angle of the illuminating light.
