Light Detection and Ranging (LiDAR)

4 LIDAR Operational Theory A pulse of light is emitted and the precise time is recorded. The reflection of that pulse is detected and the precise time is recorded. Using the constant speed of light, the delay can be converted into a “slant range” distance. Knowing the position and orientation of the sensor, the XYZ coordinate of the reflective
