Perovskite Wide‐Angle Field‐Of‐View Camera

Researchers have attempted to create wide‐angle field‐of‐view (FOV) cameras inspired by the structure of the eyes of animals, including fisheye and compound eye cameras. However, realizing wide‐angle FOV cameras simultaneously exhibiting low distortion and high spatial resolution remains a significant challenge. In this study, a novel wide‐angle FOV camera is developed by combining a single large‐area flexible perovskite photodetector (FP‐PD) using computational technology. With this camera, the proposed single‐photodetector imaging technique can obtain high‐spatial‐resolution images using only a single detector, and the large‐area FP‐PD can be bent further to collect light from a wide‐angle FOV. The proposed camera demonstrates remarkable features of an extraordinarily tunable wide FOV (greater than 150°), high spatial resolution of 256 × 256 pixels, and low distortion. It is believed that the proposed compatible and extensible camera prototype will promote the development of high‐performance versatile FOV cameras. The wide‐angle field‐of‐view (FOV) cameras (fish eye camera and compound eye camera) simultaneously exhibiting low distortion and high spatial resolution is still a huge challenge. To solve this problem, a new type of wide‐angle FOV camera is developed by combining a single large‐area flexible perovskite‐based photodetector and computational technology.
