非均匀板的晶体光学性质及光弹性材料的偏振层析成像问题
Crystal Optical Properties of Inhomogeneous Plates and the Problems of Polarization Tomography of Photoelastic Materials
摘要：
利用Jones矩阵方法，分析了由一堆弱双折射板组成的非均匀材料的晶体光学性质，并与光弹性介质中三维介电张量场偏振层析所采用的胞元模型相联系。结果表明，在一般的材料表现出“表观”的光学回转所造成的不同取向的板。在弱光学各向异性的情况下，确定了极化参数和介电张量分量之间的关系。
英文摘要：
Using the Jones matrix formalism, crystal optical properties of inhomogeneous material consisting of a pile of weakly birefringent plates are analysed in relation to the cell model adopted in polarization tomography of 3D dielectric tensor field in photoelastic media. It is shown that the material manifests in general an "apparent" optical gyration caused by different orientations of the plates. Relations between the polarimetric parameters and the dielectric tensor components are ascertained for the case of weak optical anisotropy.
