Light detection and ranging (LIDAR) is a sensing method that detects objects and maps their distances. The technology works by throwing the target with an optical pulse and measuring the characteristics of the signal received after reflection. A LiDAR system basically consists of a laser, a scanner, and a specialized GPS receiver. An optical pulse is sent by the laser, which is transmitted toward the target. The distance of the object is calculated by measuring the time taken by the pulse to ... Read more
