Abstract
An optical artificial neural network intelligent chip, a preparation method thereof and an intelligent processing apparatus. The optical filter layer serves as the input layer of the artificial neural network. The image sensor serves as the linear layer of the artificial neural network. The filtering effect of the optical filter layer on the incident light entering the optical filter layer serves as the connection weight from the input layer to the linear layer, such that the related functions of the input layer and the linear layer in the artificial neural network are achieved by the optical filter layer and the image sensor in the intelligent chip in a hardware manner, and no complicated signal processing and algorithm processing corresponding to the input layer and the linear layer need to be performed in the subsequent artificial neural network intelligent processing using the intelligent chip.
