Abstract

The polarization-encoded optical shadow-casting (POSC) system [1] has shown considerable promise in two dimensional digital image processing applications. Recently, POSC systems were utilized to perform gray level image processing [2], It is very natural for the POSC systems to operate on images which are already in two dimensional form. The generalized POSC algorithm [1] has already been used to accomodate trinary designs [3], programmable logic arrays [4], associative content addressable memories [2], carry-free adder [5], and flip-flops [6].
