| 摘 要： | 建立了偏振光在生物组织中传播的模型,并利用该模型模拟了偏振光在生物组织中传播的过程,重建了多种偏振态输入光的情况下光偏振态在生物组织中的分布及生物组织的偏振特性模型.分析了光偏振度与光被生物组织散射次数的关系,阐明了由于偏振光在组织中传播,其偏振态逐渐改变而造成的偏振OCT 干涉计两臂光束失去相干性及偏振OCT 图像质量下降现象.通过分析斯托克斯(Stokes)矢量和穆勒(Muller)矩阵在光纤型偏振OCT系统中的应用,说明Muller 矩阵不受输入光偏振态的影响,因此它比Stokes 矢量更适用于光纤型偏振OCT 系统研究.

| Abstract: | A model for polarized light propagating in the biological tissue was proposed and the propagating of polarized light was simulated with the model. The distribution of polarization in biological tissue and birefringence model of biological tissue were reconstructed with different input polarized light. The relationship between Degree of Polarization (DOP) and order of scatters shows that depolarization of polarized light propagating in tissue weakens the interference between two arms of interferometer in PS-... |
