LiDAR uses reflected light to measure distance to objects; it can be used for short-range up to a distance of ~300m LiDAR (Light Detection and Ranging) – a Time of Flight measurement Detection principle: A very short laser pulse travels from the LiDAR sensor to an object and back. The sensor measures the travelling time of the laser pulse and determines the distance and relative velocity of the object. 100 m distance 0,6 m s OSRAM Licht AG 13 LiDAR Tech Teach-In | June 20, 2018
