Abstract

A scheme is introduced and experimentally demonstrated for increasing the accuracy of an optical implementation of matrix-vector multiplication. The system is configured in a feedback loop to iteratively solve simultaneous equations. The technique is based upon a binary expansion of the matrix which is convolved with the binary expansion of the vector. This is implemented optically by the outer product synthesis of matrix products using crossed acousto-optic cells and a strobed light source.
