The contribution of multiple scattering in lidar backscattering from clouds has been investigated using a ruby laser at 694 nm. The depolarization of an incident linearly polarized signal is measured with a multichannel lidar receiver. An analysis is presented whereby this information can be utilized to measure the multiple scattering in clouds in which single scattering retains the incident linear polarization. Experimental data are presented for cumulus clouds and for ground level fog, and the results are compared with some recent theoretical computations.
利用波长为694nm的红宝石激光，研究了激光雷达从云层后向散射中多次散射的贡献。用多通道激光雷达接收器测量入射线性偏振信号的去偏振。本文提出了一种分析方法，利用该信息可以测量云层中的多次散射，其中单次散射保留入射线性偏振。给出了积云和地面雾的实验数据，并将结果与最近的一些理论计算进行了比较。
