Optical diagram of lidar The peculiarity of the optical The peculiarity of the optical diagram of the lidar is that all lidar diagram of the lidar is that all lidar signals pass through the same signals pass through the same optical path and have the same optical path and have the same geometrical function. geometrical function.
