Abstract Imaging through scattering media is widely studied in various applications including industrial inspection and autonomous driving. Most existing image sensors always suffer from the aliasing effect that generates a diffused image, leading to an extremely challenging problem recovering targets of high quality, especially for 3D imaging. In this study, scanning‐driven photon‐counting imaging system proposed via asynchronous polarization modulation. To eliminate effect, we utilize point‐to‐point scanning strategy used illuminate target detector perceive weak echo signals passing media. Then, polarization‐modulated ranging method innovatively based on Gamma pulse model calculate relative depth with consideration media's difference. Therefore, accuracy calculated generalization capability real can be significantly improved. addition, time reshaping cope ambiguity caused by measurements. experiment, variety strong verify excellent method.
