Structured Light Depth Sensors Incorporating Metasurfaces

Abstract

Systems and methods for sensing depth may utilize a baseline matrix for correlating different baselines with their corresponding centers of diffraction. In one particular example, a depth sensing system includes: a projector including: a light source and a metasurface, where the light source illuminates the metasurface at different transverse locations such that the metasurface projects light in different transverse locations onto an object; a receiver including an image sensor configured to receive light that is reflected from off the object, where the projector and the receiver are a fixed distance apart such that the light in different transverse locations has a plurality of centers of diffraction which correspond to different baselines which are the distance between the centers of diffraction and a fixed point of the receiver, and where the light received by the image sensor corresponds to different disparities based upon the depth of the object.
