利用辐射传输，我们研究了线性和圆偏振光通常撞击一个平面平行介质包含随机分布的相同大小的乳胶球在水中。本研究的重点是了解偏振光散射的基本性质。特别是，我们分析后向散射和传输通量的直接数值模拟计算的响应。从这些数值计算中，我们观察到圆偏振光以比线偏振光更慢的速率去偏振。此外，圆偏振光显示出比线偏振光更明显的散射体的大小的依赖性。此外，在圆偏振后向散射光中观察到的螺旋度翻转是由低阶散射表现的基本现象。
Using radiative transfer, we investigate linear and circular polarized light normally impinging a plane-parallel medium containing a random distribution of identically sized latex spheres in water. The focus of this study is to understand fundamental properties of polarized light scattering. In particular, we analyze backscattered and transmitted flux responses computed form direct numerical simulations. Form these numerical computations, we observe that circular polarized light depolarizes at a slower rate than linear polarized light. In addition, circular polarized light shows a more noticeable dependence on the size of the scatterers than linear polarized light. Furthermore, the helicity flip observed in circular polarized backscattered light is a fundamental phenomenon manifested by low order scattering.
