Microscopic evolution of polarization across active polarization imaging in turbid medium

Abstract

By leveraging the polarization differences between target and backscattered light, polarization imaging improves the signal-to-noise ratio. Earlier studies concentrated on the macroscopic effects of medium composition on depolarization, overlooking microscopic considerations of polarization evolution across the full imaging link. To address this, innovation involves a classification method based on differences in the scattering process to achieve microscopic decomposition of returned information. Furthermore, the non-uniform distribution of backscattered light after decomposition is presented by the angle of polarization, and the differences are quantified by the aid of the Poincaré sphere. These results contribute new ideas for polarization dehazing in turbid medium.
