Researching on single photon detection in airborne laser ranging

In this paper, the key technologies of single photon detection in airborne laser ranging are analyzed. Aiming at the engineering application, we propose the next investigation of single photon detection. 1) the compensation of pulse propagation in atmosphere; 2) the problem of ranging accuracy for moving targets; 3) high accuracy optical axis coherence of receiving and transmitting. Further research can improve the airborne adaptability of single photon ranging system.
