| 摘 要： | 介绍了平行轴与共轴激光雷达几何重叠因子的物理意义,并从几何推导和实验测量两方面给出求解几何重叠因子的方法.通过对AML-1激光雷达(共轴系统)的实验总结,列举了一些有关几何重叠因子的典型结果,并分析了激光雷达几何重叠因子对探测气溶胶消光系数的影响.最后得出,气溶胶消光系数对几何重叠因子的修正非常敏感,但在激光雷达系统稳定且操作规范的情况下,几何重叠因子随距离的分布曲线是相对稳定的,此时对气溶胶消光系数的影响也较小.

| Abstract: | Lidar geometrical form factor of coaxial and biaxial transmitter-receiver systems are described. Theoretical method and experimental ones for calculating geometrical form factor are presented. Some examples of geometrical form factor correction are introduced and the misalignment effects on aerosol extinction are analyzed based on many experiments of AML-1 lidar. It is concluded that the geometrical form factor is very sensitive to misalignment in the optical system, which would arise much more errors for the aerosol extinction. But the geometrical form factor will be stability when the lidar system is reliable and optical system is correct. |
