我们展示了一种基于光纤激光泵浦的无人驾驶飞行器(UAV)载光子计数测深激光雷达。该绿光激光器位于水的透明窗口内，能够产生宽度为280ps、中心波长为532.05 nm、脉宽为280ps的1.1W脉冲。以该绿光激光器为发射机，以光子多管为探测器，采用同轴收发结构，构成了光子计数测深激光雷达。无人机载实验是白天在海南省石梅湾海岸进行的，中国说。过滤后的点云显示，最大可探测水深约为8m，是Secchi水深的两倍，表明其具有实用激光雷达测深的能力。
We have demonstrated an unmanned aerial vehicles (UAV)-borne photon-counting bathymetric Lidar based on a fiberlaser- pumped green laser. The green laser was capable of producing 1.1 W pulses with widths of 280 ps at 500 kHz and bandwidths of 0.04 nm centered at 532.05 nm, located within the transparent window of water. The photon-counting bathymetric Lidar was constructed with this green laser served as the transmitter and a photon-multiple-tubes as the detector in a coaxial transceiver structure. The UAV-borne experiments were carried out at the coast of Shimei Bay at Hainan Province, China in daytime. The filtered point cloud shown that the maximum detectable water depth was about 8 m, two times as much as the Secchi depth, indicating its capability for practical Lidar bathymetry.
