Paper Abstract

Photo refractive multiple quantum wells (MQW) have become important for the realization of fast and two-dimensional analog optical image-processing devices. They have several interesting characteristics which make them desirable from system point of view. In this new technique the image processing can be performed in spatial domain and real time. For this purpose we used MQW diodes as detector/modulator that spatially arranged as pixels, then the input and output of the processor are in optical form. The input is a non-coherent, colored image, un-polarized and the output is a pixelated, coherent, gray scale image.
