In this paper we propose a model to understand the polarization patterns of skylight when reflected off the surface of waves. The semi-empirical Rayleigh model is used to analyze the polarization of scattered skylight; the Harrison and Coombes model is used to analyze light radiance distribution; and the Cox-Munk model and Mueller matrix are used to analyze reflections from wave surface. First, we calculate the polarization patterns and intensity distribution of light reflected off wave surface. Then we investigate their relationship with incident radiation, solar zenith angle, wind speed and wind direction. Our results show that the polarization patterns of reflected skylight from waves and flat water are different, while skylight reflected on both kinds of water is generally highly polarized at the Brewster angle and the polarization direction is approximately parallel to the water's surface. The backward-reflecting Brewster zone has a relatively low reflectance and a high DOP in all observing directions. This can be used to optimally diminish the reflected skylight and avoid sunglint in ocean optics measurements.
在本文中，我们提出了一个模型，以理解当光线从波浪表面反射时的天空光偏振模式。使用半经验瑞利模型分析散射天空光的偏振；使用哈里森和库姆斯模型分析光辐射分布；使用考克斯 - 蒙克模型和穆勒矩阵分析来自波浪表面的反射。首先，我们计算从波浪表面反射的光的偏振模式和强度分布。然后，我们研究它们与入射辐射、太阳天顶角、风速和风向的关系。我们的结果表明，波浪和平坦水面反射的天空光的偏振模式不同，而两种水面反射的天空光在布儒斯特角通常高度偏振，并且偏振方向大致平行于水面。后向反射布儒斯特区在所有观测方向上具有相对较低的反射率和较高的偏振度。这可用于在海洋光学测量中最佳地减少反射天空光并避免镜面反射光。
