标题： Spatially resolved stress measurements in materials with polarization-sensitive optical coherence tomography: image acquisition and processing aspects

摘要： 我们证明偏振敏感光学相干断层扫描（PS-OCT）适合以非接触和非破坏的方式映射材料内部的应力分布。与透射光弹性测量相比，样品不需要透明，可以是散射性质的。在单个PS-OCT延迟图像中对条纹图案进行去噪和分析，被证明是进行被研究样品内部应力状态定量全场评估的基础。 显示英文摘要

摘要： We demonstrate that polarization-sensitive optical coherence tomography (PS-OCT) is suitable to map the stress distribution within materials in a contactless and non-destructive way. In contrast to transmission photoelasticity measurements the samples do not have to be transparent but can be of scattering nature. Denoising and analysis of fringe patterns in single PS-OCT retardation images are demonstrated to deliver the basis for a quantitative whole-field evaluation of the internal stress state of samples under investigation.
