诸如偏振显微镜或偏振敏感光学相干断层扫描的偏振光学技术通常假定光垂直于样品表面，并且双折射生物组织的原纤维布置在平行于该表面的平面中。定量描述具有非平行原纤维取向和/或离轴入射的组织的偏振数据的方法通常缺乏严格的理论分析。我们提出了一个极化模型与任意的纤维取向和/或可变的入射角通过扩展的琼斯矩阵理论，极分解，和庞加莱等价定理。该模型适用于诊断或组织结构分析，适用于关节软骨。(C)2010年美国光学学会
Polarimetric optical techniques such as polarization microscopy or polarization-sensitive optical coherence tomography normally assume that light is perpendicular to the sample surface and that fibrils of a birefringent biological tissue are arranged in a plane parallel to this surface. The approaches that describe quantitatively polarimetric data from tissues with nonparallel fibril orientation and/or off-axis incidence usually lack a rigorous theoretical analysis. We present a polarimetric model with arbitrary fibril orientation and/or variable incidence angle by means of the extended Jones matrix theory, the polar decomposition, and Poincare equivalence theorem. The model, suitable for diagnosis or tissue structure analysis, is applied to articular cartilage. (C) 2010 Optical Society of America
