Lidar holds the promise of making autonomous vehicles safer by improving navigation and enabling faster, better decisions. Lidar is an acronym for light detection and ranging, and, as its name implies, is a remote sensing method using laser light to measure distance to an object. A flash or scanning lidar provides a three-dimensional point cloud of the surroundings.

Until now, lidar navigation systems relied on a first-generation pulsed technology called time-of-flight (ToF) lidar. Pulsed ToF lidar emits powerful pulses of light to detect obstacles in its path by…
