Abstract

The application of a programmable magnetooptic spatial light modulator to white-light optical signal processing is presented. We have shown that the magnetooptic device responds to the polarized white light, in which a wide range of color object patterns can be generated. Since the magnetooptic device is a transmitted type spatial light modulator, it is very suitable for real-time programmable spatial filter synthesis and object pattern generation for optical signal processings. Experimental demonstrations of some of the elementary spatial filter syntheses and pseudocolor encodings are provided.
