Measurement of optical properties of skin is an expanding and growing field of research. Recent studies have shown that the biological tissue, especially skin, changes the polarization state of the incident light. Using this property will enable the study of abnormalities and diseases that alter not only the light intensity but also its polarization state. In this paper we report an experimental study for measuring changes of polarization state of the light scattered from a phantom similar to a sample model of scattering skin. Using the notation of Stokes vector for the polarized light and Mueller matrix for the sample with its polarization properties, we have shown that some elements of the matrix were particularly sensitive to the changes of the polarization-altering physical properties of the scatterers within the phantom.
皮肤光学特性的测量是一个不断扩展且日益发展的研究领域。最近的研究表明,生物组织,尤其是皮肤,会改变入射光的偏振态。利用这一特性将能够研究不仅改变光强度而且改变其偏振态的异常情况和疾病。在本文中,我们报告了一项实验研究,用于测量从类似于散射皮肤样本模型的体模散射的光的偏振态变化。使用偏振光的斯托克斯矢量表示法以及具有偏振特性的样本的穆勒矩阵,我们已经表明,该矩阵的某些元素对体模内散射体的偏振改变物理特性的变化特别敏感。
