A modulating optical operation element is composed of a light receiving separation element having a pair of light receiving elements, a photoelectric operation element made of an operation element for calculating electric signals outputted from the light receiving separation element and outputting an electric signal in response to a result of this calculation, a transmission type light modulation element made of a transmission type liquid crystal sandwiched between transparent electrodes, and polarizers disposed on both sides of this light modulation element. An optical neuron layer for outputting an information beam consisting of light outputted from each optical neuron element is constituted by arranging a plurality of these elements in a two-dimensional pattern. A constituent unit of an optical neural network is made by the combination of this neuron layer with a weighted information beam output means for weighting a modulated information beam outputted from the neuron layer and outputting the modulated information beam. An optical neural network which acts as an optical data processing circuit is constituted by connecting a plurality of these constituent units together. <IMAGE> |
