Solid-state LiDAR chip (IMAGE) University of California - Berkeley Caption Engineers at the University of California, Berkeley, used microelectromechanical system (MEMS) switches to dramatically increase the resolution of chip-based LiDAR sensors. In this schematic of a LiDAR chip, laser light is emitted from an optical antenna connected to a tiny switch. Reflected light is captured by the same antenna. 3D images are obtained by sequentially turning on the switches in the array.
