WebLiDAR is an acronym for Light Detection and Ranging. In LiDAR, laser light is sent from a source (transmitter) and reflected from objects in the scene. The reflected light is … WebLIDAR ("light detection and ranging") devices emit pulses of infrared laser light that reflect off of the target vehicle and return to a receiver in the unit. The device measures the distance between the LIDAR and target vehicle based on the time it takes the light to travel back to the device.
