A lateral shearing interferometer designed and built for the study of the precorneal tear film topography dynamics and its effect on visual performance is presented. Simple data processing algorithms are discussed and tested on data illustrating different tear topography features: postblink tear undulation, tear breakup, eyelid-produced bumps and ridges, bubbles, and rough precontact lens tear surfaces.
本文介绍了一种为研究角膜前泪膜地形动力学及其对视觉性能的影响而设计和制造的横向剪切干涉仪。文中讨论了简单的数据处理算法，并在展示不同泪膜地形特征的数据上进行了测试，这些特征包括眨眼后泪膜波动、泪膜破裂、眼睑产生的凸起和隆起、气泡以及接触镜前粗糙的泪膜表面。
