主 题：visual perovskite image
摘 要：There are two primary types of photoreceptor cells in the human eye:cone cells and rod cells that enable color vision and night vision,***,inspired by the function of human visual cells,we develop a high-resolution perovskite-based color camera using a set of narrowband red,green,blue,and broadband white perovskite photodetectors as imaging *** narrowband red,green,and blue perovskite photodetectors with color perceptions mimic long-,medium-,and short-wavelength cones cells to achieve color imaging ***,the broadband white perovskite photodetector with better detectivity mimics rod cells to improve weak-light imaging *** perovskite-based camera,combined with predesigned pattern illumination and image reconstruction technology,is demonstrated with high-resolution color images(up to 256 x 256 pixels)in diffuse *** is far beyond previously reported advanced perovskite array image sensors that only work in monochrome transmission *** work shows a new approach to bio-inspired cameras and their great potential to strongly mimic the ability of the natural eve.
