摘要

We have constructed an optical neural-network system with learning capability by using a pockels readout optical modulator. The system has a two-dimensional structure that permits easy optical alignment and can handle images without scanning. Learning signals are calculated optically with two liquid-crystal devices by a matrix-matrix outer-product method. The calculated learning signals are added directly to the weights memorized on the Pockels readout optical modulator, A two-layer network is implemented, and the learning and recgnition of four alphabetical characters are realized according to the delta rule. #1998 Optical Society of America OCIS codes: 200.4260, 200.4860, 230.4110.
