a (Top) Illustration of polarized light generation methods transitioning from circular to linear polarization. (Bottom) Display of polarized light variations achieved through the adjustment of the angle of a half-wave retarder. b Responsivity of R-form and S-form CIPs to linear and circularly polarized light. c Time-resolved photocurrent measurements to characterize R-form and S-form CIP behavior with a half-wave retarder rotating six times at a uniform speed. d Schematic of a 1 × 1 polarimetric array with integrated localized CLCN on vdW photodiodes. e Photocurrent behavior of the 1×1 array under LH-CPL and RH-CPL illumination. f Vout of the 1 × 1 array as the polarization state varies. g Schematic of a 1 × 3 polarimetric array illustrating analog convolution of incident light and CIP responsivities. h Circuit illustration polarimetric kernel consisting of Sobel-X (R-form) and identity (S-form). i Measured voltage signal over time during a 904 nm spot scan across the array under different polarizations. j Spatially processed voltage signals by polarimetric kernel array.
