Ferroelectric modulated visual devices with spatial and temporal polarization‐sensitivity for information recognition and processing in visibility‐degraded environments

InfoMat, EarlyView.
Conventional imaging systems often struggle to recognize objects accurately in challenging environments such as underwater or foggy scenes. We developed a polarization‐sensitive artificial vision device inspired by the mantis shrimp that uses advanced two‐dimensional materials and a ferroelectric layer to directly sense, process, and retain visual ...
