Abstract

In this presentation, I will introduce the result of a metasurface-based compact depth sensing system that can be applied to LiDAR. I will explain the design principle of this structured light metasurface which can spread the point cloud with a large field of view angles. This spread point cloud is captured by two distinct cameras, and depth information is computed by the stereo-matching method. And I will suggest electrically tunable metalens which can be easily integrated with not only AR/VR systems but also electronic systems. These metaphotonic devices have the potential to be applied to various fields such as mobile sensors, biometric security systems, autonomous driving, metaverse, and driver assistance.
