Paper Abstract

An optical neural network system using a microchannel plate spatial light modulator (MSLM) and a computer-generated hologram (CGH) displayed on a liquid crystal TV (LCTV) display device are described. In the optical three-layer neural network, the back-propagation learning algorithm is successfully demonstrated with the uniformity of +/- 35% in synaptic connection coefficients in MSLM and the contrast of 20 in neuron output in LCTV, respectively. To make a dynamic optical interconnection and analog optical computing, CGHs are displayed on LCTV. Applications of displaying CGHs, spatial filtering, and moving pictures are performed.
