Abstract

Optical Boolean logic gates are the basic elements in a digital optical computer. We discuss a system that can perform all sixteen basic two-operand Boolean operations with one MSLM and three LCTVs. The MSLM is used as an adder, subtractor, inverter, or just as a buffer. The LCTVs are used with a microcomputer as programmable input interfacing devices. The basic advantage of the system is the real-time programmable processing capability. Adding a feedback loop to the system, its function can be expanded to execute consecutively Boolean calculations.
