Abstract
3-D sensing is a rapidly evolving technology impacting broad applications in computer vision. Existing 3-D cameras are restricted in field of view, resolution, and feature a complex multiple lens assembly. Here, we demonstrate a single piece fish-eye metalens in the visible band capable to perform diffraction-limited focusing and imaging over nearly 180-degree field of view. Our metalens has been shown to produce panoramic high-resolution imaging of a semi-circular target. Furthermore, we constructed a stereoscopic camera and performed panoramic depth measurements. We believe that the fisheye-metalens 3-D sensors is a promising platform empowering a range of emerging high-tech sectors.
