Content-addressable-memory-based single-stage optical modified-signed-digit arithmetic
Yao Li, Dai Hyun Kim, Andrew A. Kostrzewski, George Eichmann · Optics Letters · 1989
Using a novel nonholographic optoelectronic content-addressable memory in a free-space angular multiplexing geometry, a single-optical-stage compact parallel optical modified-signed-digit arithmetic processing architecture is proposed. Some spatial light modulator based experimental results are also presented.
