a Schematic diagram of CPL imaging. b Object and measured weights of the object images in the initial state after a sequence of 395 nm LCP and RCP spikes (10 \(\mu\)W cm−2, 1 Hz) by the PAS array with schematic experimental setup shown in Fig. 3a. c Schematic structure of PAS device based neural network. d CPL-dependent recognition accuracy and loss variation of the SNNs during 300 training epochs. e Recognition accuracy to every target after the training of SNNs under LCP spikes.
