摘要
介绍了一种新型光学测量技术——剪切电子散斑技术的改进与应用,它是一种有效的基于激光技术,测量三维物体表面变形和形貌的非接触测量方法。与传统方法相比,改进后的方法光路结构和采用的算法更加简单,可广泛应用于表面应变、张力、材料特性的测量,残余应力的估计,表面泄露的监测以及物体表面三维形貌测量等领域。
The improvement and application of a novel optical measurement technique-shearography are presented. This improved measurement is a laser-based technique for full-field, non-contacting measurement of 3D surface deformation and profile,and its structure and arithmetic are simpler compared with the conventional method. Other applications of shearography include surface strain and stress measurement, material characterization, residual stress evaluation, surface leak detection and 3-D surface shape measurement.
