青光眼是视力受损的主要原因，早期诊断对成功治疗至关重要。研究表明，成像偏振法在视网膜结构变化的早期检测中具有优势。在这里，我们从理论上和实验上提出了一种快照穆勒矩阵偏光计眼底相机，它有可能记录视网膜的偏振变化特征。它是通过将偏振光栅集成到眼底相机设计中而制成的。通过分析投影到像面上的偏振条纹，可以得到完整的穆勒矩阵数据集。在本文中，我们描述了快照视网膜成像穆勒矩阵偏光计（SRIMMP）的实验实现，重点介绍了与校准相关的问题，并提供了从相机获取的初步图像。
Early diagnosis of glaucoma, which is a leading cause for visual impairment, is critical for successful treatment. It has been shown that Imaging polarimetry has advantages in early detection of structural changes in the retina. Here, we theoretically and experimentally present a snapshot Mueller Matrix Polarimeter fundus camera, which has the potential to record the polarization-altering characteristics of retina with a single snapshot. It is made by incorporating polarization gratings into a fundus camera design. Complete Mueller Matrix data sets can be obtained by analyzing the polarization fringes projected onto the image plane. In this paper, we describe the experimental implementation of the snapshot retinal imaging Mueller matrix polarimeter (SRIMMP), highlight issues related to calibration, and provide preliminary images acquired from the camera.
