The compound eyes of natural insects endowed with the merits of a wide field of view (FOV), high sensitivity, and detection of moving targets, have aroused extensive concern. In this work, a large-scale artificial compound eye is fabricated by a high-efficiency and low-cost strategy that involves the combination of the thermal reflow method and pressure deformation. About 30,000 ommatidia are evenly distributed on the surface of a hemisphere with an ultralow surface roughness and a large numerical aperture (NA) of 0.66. Moreover, the FOV of the artificial compound eye investigated is about 120°. The collaboration of the compound eye and CMOS sensor makes the ommatidia capturing multiple images of human organs enabled. This micro-based imaging system has considerable potential in integrated pinhole cameras, medical endoscopes, and drone navigation.

通过在CMOS传感器上集成仿生人工复眼形成的高数值孔径成像系统

天然昆虫的复眼具有视场宽、灵敏度高、检测运动目标等优点，引起了广泛关注。在这项工作中，通过热回流方法和压力变形相结合的高效低成本策略制造了大规模的人工复眼。约 30,000 个小眼均匀分布在具有超低表面粗糙度和大数值孔径 ( NA)的半球表面) 的 0.66。此外，所研究的人造复眼的 FOV 约为 120°。复眼和 CMOS 传感器的协作使小眼能够捕捉人体器官的多个图像。这种基于微型的成像系统在集成针孔相机、医疗内窥镜和无人机导航方面具有相当大的潜力。
