Abstract
A chiral light-field optical imaging camera incorporating an array of photonic spin-multiplexed bifocal metalenses. Combined with a novel deep learning-based neural network reconstruction algorithm, the system provides distinct aberration-free photographic capabilities, including the ability to achieve a polarization controllable extremely large depth-of-field optical imaging across a range of distances within a range covering at least five orders of magnitude in absence of moving a part of the camera and based on a single exposure of an optical detector while maintaining high spatial lateral resolution.
