Fig. 1From: The use of terrestrial LiDAR technology in forest science: application fields, benefits and challengesOperating principle of a terrestrial LiDAR (light detection and ranging) scanner (FARO Photon 120). A laser beam deflected by a rotating mirror scans a vertical plane, and the complete rotation of the device allows hemispherical scanning. This results in the digitisation and the representation of surrounding objects in a three-dimensional (3D) point cloudBack to article page
