Complementary-encoding photorefractive optical processor for truth-table lookup.
A photorefractive optical processor that uses complementary encoding is presented for the real-time implementation of truth-table lookup. Recording a multiexposure hologram in a photorefractive crystal permits different truth-table patterns to be stored. The processor is capable of performing the functions of full addition, half-addition, subtraction, multiplication, and the calculation of complex multinominal with any number system.
