What is optical strain measurement technology

我们常说的光学应变测量，一般是说测量样品的光学透过率，有时候也有需要测红外透过率和紫外透过率，此项技术在很多领域都能用到，太阳膜、玻璃、PC材料，手机盖板，只要是需要透光的材料都有可能要测。运用的原理是透过率原理，即入射光强前后的对比。

工业光学测试设备，包括三维光学扫描、三维光学全场应变测试、三维光学高速应变测试、薄板成形网格应变测量、三维运动捕捉等。

光学测量利用具有对比度的图像信息，计算出应变、位移和形貌。无需连接任何单独的接触式传感器，如应变计、LVDT或加速度计；无需校准单个接触式传感器；无需进行信号调节无需辅助夹具作为LVDT的参考框架。

借助全场的高分辨率测量数据，可以获得局部区域的变形效应，因此可以进行详细分析，例如：吕德带（明显的屈服效应）、流动前沿 Flow fronts、颈缩与失效。

此外，光学测量比较传统测量的优势还有非常的多。可以在关注本站点看到更多知识和相关领域的应用。
