Abstract
Compound eyes of insects are great optical system for imaging and sensing by the nature creator, which is an unsurpassed challenge due to its precision and small size. Here, we use meta-lens consisting of GaN nano-antenna to open the fascinating doorway to full-color achromatic light field imaging and sensing. A 60×60 multi-channels meta-lens array is used for effectively capturing multi-dimensional optical information including image and depth. Based on this, the multi-dimensional light field imaging and sensing of a moving object is capable to be experimentally implemented. Our system presents a diffraction-limit resolution of 1.95 micrometer via observing the standard resolution test chart under white light illumination. This is the first mimic optical light field imaging and sensing system of insect compound eye, which has potential applications in micro robotic vision, non-men vehicle sensing, virtual and augmented reality, etc.
