What is a LiDAR?
LiDAR (Light detection and ranging) is a remote light measurement tool. Therefore, this device is based on the principle of remote sensing laser telemetry. Lasers are sent in different directions over 360 °. Each beam of light is reflected on one or more objects, then returns to the receiver. By calculating the time elapsed between the emission of the pulse and its reception and knowing the speed of light, the LiDAR system can thus measure the distance between the source and the target.
