视网膜双折射扫描(RBS)是一种用于远程无创检测眼睛注视的新技术。该方法基于对视网膜引起的极化变化的分析。在这项研究中，对RE的原理进行了数学建模，以便于更好地理解所获得的信号的来源。利用Poincare球面表示增强了Stokes向量分析和Mueller矩阵乘法。角膜被建模为线性延迟器。中心凹区域被模拟为径向对称的双折射介质。该模型准确地预测了在中心和旁中心固定期间获得的RES信号的频率和相位。在Res期间显示中心固定的信号可能是Henle纤维的径向双折射和覆盖在其上的角膜双折射的组合。(C)1999年美国光学学会[S0740-3232(99)01309-5]。OCS码：070.6020、120.5410、170.4460、170.4470、330.4300。
Retinal birefringence scanning (RBS) is a new technique that is used to detect the fixation of the eye remotely and noninvasively. The method is based on analysis of polarization changes induced by the retina. In this study, the principles of RES were mathematically modeled to facilitate a better understanding of the origins of the signals obtained. Stokes vector analysis and Mueller matrix multiplication were augmented with Poincare sphere representation. The cornea was modeled as a Linear retarder. The foveal area was modeled as a radially symmetric birefringent medium. The model accurately predicted the frequency and phase of RES signals obtained during central and paracentral fixation. The signal that indicates central fixation during RES likely results from a combination of the radial birefringence of the Henle fibers and the overlying corneal birefringence.
