Computational imaging is an advanced field that merges computational algorithms with smart optical design to extract more information from visual data than traditional imaging methods can achieve. Computational imaging aims to overcome the limitations of conventional 2D imaging, which can be hindered by physical constraints such as aberration, noise, and exposure time. However, most of the computational imaging technologies are limited to universal applications. We propose the meta-imaging sensor and wide-field wavefront sensor that enable multi-site aberration estimation and correction across various applications without necessitating additional hardware modifications to the optical frontend. Our methods open new avenues for applying computational imaging technology in fields such as remote sensing, astronomical observation, industrial inspection, autonomous driving and precise healthcare.
