Visualization of a Metalens Designed for Compact Depth Sensing

Caption

Visualization of a metalens designed for compact depth sensing. It consists of subwavelength-spaced square nanopillars. By alternating two different nanopillar patterns, visualized here in red and blue, this metalens forms two images at the same time. The two images have different amounts of defocus, and they mimic the images captured by the layered retina structure in the principal eyes of jumping spiders.
