我们开发并优化了一种定制的动态电子散斑干涉仪（d-ESPI），用于测量眼组织膨胀测试过程中随时间变化的三维（3D）表面位移。以橡胶模体和人眼后巩膜的简化试验用例为例，在动态加载条件下对三维位移场进行了解析。我们介绍了d-ESPI的光学布局和校准过程，并演示了如何在试件变形速率高达6 μ m/s的情况下准确地解析位移场。(C) 2018年Elsevier Ltd.出版
We developed and optimized a custom dynamic Electronic Speckle Pattern Interferometer (d-ESPI) for measuring time-dependent three-dimensional (3D) surface displacements during inflation testing of ocular tissues. The 3D displacement field was resolved under dynamic loading conditions for a simplified test case of a rubber phantom and a real-world test case of the posterior sclera of a human eye. We present the optical layout and calibration procedure of the d-ESPI, and demonstrate how the displacement field can be accurately resolved for specimen deformation rates up to 6 mu m/s.
