提出一种测量大气气溶胶散射相函数及能见度的方法，并且设计了以半导体激光器为光源和电荷耦合器件(CCD)为探测器的实验装置，利用该实验装置测量了15°~45°的散射灰度值角分布。根据激光雷达方程和Henyey-Greenstein散射相函数理论，拟合气溶胶的相函数分布，计算其能见度。将拟合得到的相函数和计算的能见度的结果分别与POM天空辐射计和Belfort能见度得到的观测结果进行对比，结果表明两者一致性较好，证明了利用激光光源和CCD测量气溶胶相函数和能见度的可行性。

A new method is presented to measure aerosol scattering phase function and visibility, and an experimental system which uses semiconductor laser as the light source and charge coupled device (CCD) as the detector of scattering light is constructed. The grey level of 15°~45° distribution is measured by the system. The aerosol scattering phase function is fitted and the atmospheric visibility is calculated based on the method. The results have good agreement with the results of POM sky radiometer and Belfort visibility meter, and this method is feasible to measure aerosol scattering phase function and visibility.
