Implementation of Boolean logic gates using a microchannel spatial light modulator with liquid-crystal televisions

A programmable optical system that can perform binary Boolean logic operations with a microchannel spatial light modulator (MSLM) is presented. The MSLM is used as an adder, an inverter, a subtractor, or a buffer. We used three liquid-crystal televisions with a computer as input interfacing devices. Through the use of its feedback loop, the system can consecutively execute a series of logic operations. Experimental results are provided.
