| 摘 要： | 测量了不同人土雾浓度下垂直偏振入射光的透射光强。利用实验数据，分析了垂直、平行方向上透射光强的变化趋势。得出平行偏振分量透射光强大致呈指数下降的趋势，垂直偏振分量透射光强先略微上升而后下降。由退偏振度随雾浓度的变化讨论了退偏产生的原因，指出雾浓度较低时，雾滴可近似视为球形。基于光的偏振特性，从理论上分析并计算得到光在雾中传输时透射、散射光强。实验结果对研究光在雾中传输及分析大气中雾对透射光偏振态的影响有一定的参考价值。

| Abstract: | Transmission intensity of vertical polarized incident light under different artificial fog concentrations was experimentally measured, and based on the experimental data, changes in relative vertical and parallel transmission intensity were analyzed. Results show that the parallel transmission intensity approximately shows an exponentially decline distribution while the vertical one displays a rising-then-declining trend. Using the degree of depolarization, cause of depolarization was discussed, and the droplet can be viewed as a sphericity in the lighter fog. Based on the characteristic of polarized light, transmission intensity and scattering intensity were calculated. The experiment is valuable in study of the light transmission in fog and in analyzing the effect of fog on laser radiation polarization in the atmosphere. |
