Abstract

A bichannel optical shadow casting (OSC) technique has been proposed for logic operation and addition of multi-bit binary numbers. In case of addition the “carry” is accomodated by spatial placement of channels. Optoelectronic half and full adders, using spatial light modulators (SLM), optical to electrical converters, beam splitters and mirrors, form additional building blocks in the proposed processor, where operations are performed in parallel. Limitations are discussed.
