Abstract

This paper presents a new optical method for density pseudo-coloring that the color can be adjustable. This method is based on the technique for phase image pseudo-coloring and realizes adjustable pseudo-coloring by using the diffraction effect of dual gratings and filtering technique in white-light system. First the paper proves the principle of the method. Then it verifies the validity of the theory by experiment. Finally certain images are processed. Both the theory and the experiment show that the new method is effective.
