| Abstract: | Photon counting Lidar, in which single photon detector with high sensitivity has been used, is a new laser ranging technology of great potential and advantages. The sensitivity of Lidar system could be improved by 2 or 3 magnitudes. In this paper, the principle of photon counting laser ranging is discussed and analyzed, as well as the advantages of it. A Geiger-mode avalanche photodiode based photon counting Lidar system was designed. Photon counting laser ranging experiments were carried out with this system. The results showed that laser ranging could be achieved with 6.23cm whole ranging accuracy under the condition of single photon sensitivity and strong background light noise. |
