气溶胶散射光偏振特性的测量与分析,对求得气溶胶的尺度谱、数密度、形状和折射率等数据,以及反 演大气的光学和物理参数有着重要的意义。 简要介绍了多角度偏振浊度计的测量原理,详细介绍了针对该仪器的扫描结构,如何完成在不同散射角上对偏振测量角度的控制。

The measurement and analysis on the polarization of light scattering by aerosol particles are significant for research on atmospheric optics and physics. The measuring principle of the multi-angle polarization nephelometer is simply introduced, and the control of the polarizing angle on different scattering angle for the scanning mechanism in this instrument is discussed in detail.
