Associative polarization-encoded optical shadow casting: gray-level image encoding for serial and parallel operations

Not Accessible

Your library or personal account may give you access

Abstract

An efficient algorithm for designing a serial and parallel multioutput logic unit using an associative polarization-encoded optical shadow-casting technique is presented. Devices designed as such have a unique content-addressable associative memory where each of the memory locations has dual addresses. For illustration, the proposed algorithm has been used to design a serial-output and a parallel-output 2-bit gray adder.
