System of laser actively evading flying objects based on image acquisition using CCD
Lidars emit high intensity of laser beam to the sky, which has a potential threat to the flyers. For the flight safety and the safe operation of lidar, a method was proposed for laser actively evading flying objects and an experimental setup was built up. The system utilized a CCD to achieve image acquisition of the airspace around the lidar emitting beam in real time. The images were transmitted to the PC and processed by the control software. Finally the shutter in the lidar emitting path was controlled to turn on or turn off according to the results of the imaging process. When flyers fly into the field of view of the CCD, the shutter can be turned off automatically to cut off the laser emission path so that to ensure the flight safety and the safe operation of lidar.
