Working principle of the chiral metasurface based polarimetry.

Caption

a, an illustration of the polarimetry based on interferometric method, the tri-channel metasurface enables the extraction of the amplitude ratio and phase difference of the RCP and LCP components for polarization analysis. b, Neural network architecture for the polarimetry. Focal plane images with data augmentation are the input of the neural network. Output is the corresponding calculated or real S parameters of the input data. c, Spatially nonuniform polarization analysis. Left is the schematics of the polarization distribution of a vector beam, right is the measured results. d, Distinction of the glasses with similar morphology features while different functions, left is sun glasses, right is the 3D glasses.
