LiDAR is an instrument to measure the contour and shape of the environment and ground. It recoils a laser beat off a target and measures the time each pulse traveled. This science is based on physics of optics and light, and measuring wavelengths in nanoseconds. The technology has taken the auto world to a new level by providing the gears needed for safe navigation. The sensors are widely used to mechanize driving of vehicles through hindrance detection and avoidance. 更多
