WebTechnical details. Airborne lidar operates by using a pulsed laser beam fired from a plane. The beam is most commonly scanned from side to side as the aircraft flies over the survey area. It measures between 20,000 to 100,000 points per second to build an accurate, high resolution model of the ground and the features upon it. WebCompared to the pulsed time-of-flight method, frequency-modulated continuous-wave (FMCW) LiDAR has been proven effective in providing high-resolution distance and velocity measurements without requiring fast electronics, and is intrinsically immune to interference from ambient light and other LiDAR transmitters. Figure 1: Principle of FMCW LiDAR.
