Space–time-sharing optical neural network
Francis T. S. Yu, Xiangyang Yang, Taiwei Lu · Optics Letters · 1991
A space-time-sharing optical neural network for implementing a large-scale operation is presented. If the interconnection weight matrix is partitioned into an array of submatrices, a large space-bandwidth pattern can be processed with a smaller neural network. We show that the processing time increases as a square function of the space-bandwidth product of the pattern. To illustrate the space-time-sharing operation, experimental and simulated results are provided.
