A study of polarized light transport in scattering media exhibiting directional anisotropy or linear birefringence is presented in this paper. Novel theoretical and experimental methodologies for the quantification of birefringent alignment based on out-of-plane polarized light transport are presented here. A polarized Monte Carlo model and a polarimetric imaging system were devised to predict and measure the impact of birefringence on an impinging linearly polarized light beam. Ex-vivo experiments conducted on bovine tendon, a biological sample consisting of highly packed type I collagen fibers with birefringent property, showed good agreement with the analytical results.
本文介绍了在具有方向各向异性或线性双折射的散射介质中偏振光传输的研究。这里提出了基于面外偏振光传输来量化双折射排列的新颖理论和实验方法。设计了一个偏振蒙特卡罗模型和一个偏振成像系统，以预测和测量双折射对入射线性偏振光束的影响。在牛腱上进行的体外实验表明，牛腱是一种由具有双折射特性的高度密集的I型胶原纤维组成的生物样本，实验结果与分析结果吻合良好。
