Measurement of Strain Based on Electronic Shearing Speckle Pattern Interferometry

摘要: 介绍了基于电子错位散斑理论的应变检测技术，并采用统计光学的方法对散斑现象进行了分析，与传统光学的分析方法相比，该方法可以对电子散斑干涉行为有更深入的理解。最后提出应变检测所需要的主要数学计算方法。

Abstract: A review of strain measurement based on electronic shearing speckle pattern interferometry(ESSPI) was presented. Some concepts on speckle pattern were addressed on the basis of speckle statistic optics, which was superior to traditional optics in understanding speckle interfering behavior. Finally, strain measurement formula was derived.
