摘要

A liquid crystal cell includes a polariser having an electrically insulating or semiconductive substrate having on its surface a series of ridges composed of a conductive material such as aluminium. The ridges act as an alignment layer and may also be connected to an electrical contact and are produced by oblique evaporation. A linear algebraic processor is formed by such a liquid crystal device 3 disposed between light emitting diode strips 4 and photodiode strips 8. Optical attentuation brought about by the liquid crystal device represents the values of an output vector while the outputs of the photodiodes represent the product of the input vector and the matrix. The processor may form part of a neural network. IMAGE
