Apply of Holography Interference in Optical Image Processing

A technigue for image processing holographic interference is presented. It is used in not only coherent image processing but also incoherent image processing, and gets high resolving prower. The optical intensity distribution of output image is propertional to optical intensity distrisbution of input image. The experimental results of pseudocolour encoding of image, white-light image subtraction and coherent image differentiation are also given.
