Abstract
A simple method for adjusting pseudocolor distributions of photographic images is described and demonstrated experimentally. This method is based on the technique for photographic phase image pseudocolor modulated by a grating. A reflecting ray path is introduced into a 4f system to produce diffraction of the dual-phase grating so that the pseudocolor at the output plane can be adjusted. The merit of this method is that many pseudocolor images with different color distributions can be obtained for each diffraction order.
