Depth Sensors (IMAGE) Proceedings of the National Academy of Sciences Caption Compact single-shot depth sensors enabled by nanostructured flat lenses (i.e. metalenses). The flat lens (shown in the middle) captures images of a 3D scene, for example candle flames placed at different locations (left), and produces a depth map (right) using a computer vision algorithm inspired by the eye of jumping spiders. The color on the depth map represents object distance. The closer and farther objects are colored red and blue respectively. Credit Image courtesy of Qi Guo and Zhujun Shi.
