自动驾驶汽车、无人机和其他自主系统依靠摄像头、雷达和超声波探测器等多种传感器来观察周围环境。光探测和测距（激光雷达）是最精确的传感器之一，可在空间中快速引导激光束，并可创建高分辨率 3D 地图。现有的激光雷达系统基于机械光束控制，因此体积庞大、价格昂贵、容易出现机械故障并且功耗较大。
Self-driving cars, drones, and other autonomous systems rely on a number of sensors such as cameras, radars, and ultrasonic detectors to observe their surrounding environments. Light detection and ranging (lidar), where a laser beam is rapidly steered in space, is among the most accurate sensors and enables creation of high-resolution 3D maps. Existing lidar systems are based on mechanical optical beam steering, and as such, are bulky, expensive, susceptible to mechanical failures, and consume large power.
