Abstract

Read online

3D depth sensing with structured light enables simultaneous imaging of multiple objects, but has limited field of view and low efficiency. Here, the authors demonstrate 3D imaging with scattered light from a metasurface composed of periodic supercells, covering a 180° field of view with a high-density dot array.
