DataSheet1_Hydrosol Scattering Matrix Inversion Across a Fresnel Boundary.PDF

We exhibit a proof-of-concept laboratory study for inversion of the partial Mueller scattering matrix of hydrosols from polarimetric observations across a smooth Fresnel boundary. The method is able to derive the 9 Mueller matrix elements relating to linear polarization for scattering angles between 70 and 110°. Unlike prior studies of this nature, we utilize measurements from a hyper-angular polarimeter designed for passive remote sensing applications to derive the Mueller matrix, and tailor the polarimetric data reduction approach accordingly. We show agreement between the inversion results and theoretical Mueller matrices for Rayleigh scattering and Mie theory. The method is corroborated by measurements made with a commercial LISST-VSF instrument. Challenges and opportunities for use of the technique are discussed.

本实验室研究提出了一种从平滑菲涅耳边界极化观测中反演水溶液部分穆尔散射矩阵的概念验证。该方法能够推导出与线性偏振相关的9个穆尔矩阵元素，适用于散射角在70°至110°之间的情况。与先前的同类研究不同，本研究利用专为被动遥感应用设计的超角极化仪进行测量，以推导穆尔矩阵，并据此调整极化数据降维方法。我们展示了反演结果与瑞利散射和米氏理论的理论穆尔矩阵之间的吻合度。该方法通过使用商业LISST-VSF仪器进行的测量得到了验证。此外，还讨论了该技术的挑战与机遇。
