Abstract

Optical shadow-casting based edge detection is hardware implemented using the spatial light rebroadcasting (SLR) materials. The digitized input image is encoded in accordance to the polarization-encoded optical shadow-casting design algorithm. An edge-detection operation of the coded image is performed using the SLR material both asspatial light modulator and logical device.
