Lidar-on-a-chip holds promise for low-cost autonomous driving systems — new Stanford research
Lidar, shorthand for “light detection and ranging,” is conceptually the same as radar except it uses light instead of radio waves to “see” things not visible to the human eye. Lidar units do a better job of detecting living things like people and dogs than radar units, but radar is better at penetrating fog, smog, rain, and other atmospheric anomalies.
