Abstract

A unique bifocal compound eye visual system is found in the extinct trilobites Dalmanitina socilis which enabled them to be sensitive to the light-field information and simultaneously perceive both close and distant objects in the environment. Here, inspired by the optical structure of their bifocal compound eye, we demonstrate a novel light-field imaging camera incorporating a photonic spin-multiplexed bifocal metalens array able to achieve both high- throughput and high-resolution light-field imaging with extreme depth-of-field. Furthermore, by leveraging a multi-scale convolutional neural network based aberration correction algorithm, we capture full-color images over a continuous depth-of-field ranging from 0.3 m to 300 m. Our results demonstrate elegant integration of nanophotonic technology with computational photography, and is expected to enable development of novel light-field imaging systems for microscopy, imaging and virtual reality applications.
