Illustration of metalens designed for compact depth-sensing

An illustration of a metalens, designed for compact depth sensing which 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 that mimic the images captured by the ...This is an NSF Multimedia Gallery item.
