Abstract

Informing vehicular and robotic devices with vision systems that can distill relative motion in complex social environments is a pressing need. Low resolution imaging has been shown to provide lower level organisms with quick response times. Here, we propose the use of a metasurface-based imaging system to capture several perspective views and image them directly onto one CMOS camera. Given the single camera, and multiple focal perspectives, the lens angles are inherently skewed and thus lead to the design of asymmetric metasurface lens profiles. The design and optimization of these asymmetric metasurfaces, each composed of 640,000 unit cells, are carried out for a series of off-axis lenses in the imaging array, with an operating wavelength of 0.98 µm. By integrating several images at different angles, the system aims to capture auxiliary data about a scene including distance data, like that acquired via stereovision, but in this case using only a single detector.
