| 摘 要： | 为了研究激光束在大气中的漂移情况,对激光束在大气中的传输做了实验研究。采用电荷耦合器件CCD成像技术对光斑的漂移情况进行了测量。对光斑漂移在水平和垂直方向的变化进行了实验研究,并分析了横向风对光束漂移的影响,得到了在不同时刻以及不同传输距离情况下光束漂移情况的实验结果。结果表明,光束随传输距离的增加,垂直和水平方向的漂移量逐渐趋于一致。

| Abstract: | For studying the wander of laser beam through atmosphere,the propagation of a laser beam through atmosphere was studied experimentally.The wander of light spots was measured by means of CCD imaging technique.The spot wander in horizontal and vertical direction was studied and the influence of crosswind on the spot wander was analyzed.The spot wander was obtained at different time and distance.The experimental result shows that the spot wander in both the directions can reach unanimity gradually with the increasing distances. |
