FPM has high requirements for the system construction and data acquisition processes. In this paper, we
propose a Fourier ptychography multi-parameter neural network (FPMN) with composite physical prior
optimization. A hybrid parameter determination strategy combining physical imaging model and data-driven
network training is proposed to recover the multi layers of the network corresponding to different physicalparameters.

We propose a method for detecting phase mismatching by using an optical sideband, which imprints a phaseshift on the pump light. By measuring this phase shift, phase mismatching can be detected for feedback
control.

our own designed software, it can collect 3-D spectral images from each spectral band simultaneously and it
