a Schematic diagram of the testing setup. b Normalized absorption spectra of PEA₂SnI₄ microwires at different angles. c Polar diagram of anisotropic absorption values of microwires at different polarization angles at 647 nm. d ΔEPSC of the device stimulated by 30 pulses at 0° and 90° polarization angles (520 nm, 7.56 mW cm⁻²). e Dynamic response of ΔEPSC to five consecutive pulses under different polarized light stimulations (520 nm, 2.26 mW cm^–2) and (f) the corresponding peak polar diagram. The simulated polarization imaging landscape map at (g) 0° and (h) 90° polarization angles processed by the imaging system, and (i, j) corresponding histograms of the corresponding pixel distributions for each output image.
