In several optical technologies for glaucoma diagnosis, polarized light is used to assess the retinal nerve fiber layer (RNFL) of the eye. For better understanding of the polarization properties of the RNFL, it was modeled as a thick birefringent slab containing parallel light-scattering cylinders, and the Mueller matrix for reflectance was derived. The model predicts that (1) the RNFL reflectance has weak intrinsic diattenuation; (2) the diattenuation spectrum depends strongly on the relative refractive indices of the cylinders; (3) both scattering and birefringence contribute to retardation; and (4) the RNFL reflectance generally preserves polarization, but depolarization may be detectable for thick RNFL at short wavelengths.
在几种用于青光眼诊断的光学技术中，偏振光被用于评估眼睛的视网膜神经纤维层（RNFL）。为了更好地理解RNFL的偏振特性，将其建模为包含平行光散射圆柱体的厚双折射平板，并推导了反射率的穆勒矩阵。该模型预测：（1）RNFL反射率具有较弱的固有二向色性；（2）二向色性光谱强烈依赖于圆柱体的相对折射率；（3）散射和双折射都对相位延迟有贡献；（4）RNFL反射率通常保持偏振，但在短波长下，对于厚RNFL可能检测到去偏振。
