| 摘 要： | 介绍了非共轴激光雷达几何因子的物理意义,通过数值模拟分析了激光雷达各系统参数包括：激光发散角、接收视场角、光轴间距、光轴失调夹角对几何因子的影响。结果表明：光轴离轴失调对激光雷达影响最大,在系统设计时应极力避免。结合自行研制的CSY2型能见度激光雷达,将理论计算与实验测量值进行对比,实验结果表明两种计算结果基本一致。

| Abstract: | The physical meaning of the anti-coaxial lidar geometrical factor was introduced.The influence of system parameters of lidar on geometrical factor was analyzed through numerical simulation.These parameters include laser beam divergence,receiver field of view,distance between two optical axes,and angle of misaligned optical axes.The result indicates that the highest influence on geometrical factor is angle of misaligned optical axes.As an example,the geometrical factor of CSY2 portable visibility lidar made in Naval University of Engineering was discussed,and then the two methods were compared. |
