摘要
首次将相移技术应用于频闪数字散斑干涉计量中,对物体的振动进行了定量分析.实验证明,这种方法有广泛的实用价值.另外,介绍了一套自动分析系统,讨论了各参数对测量结果的影响.
A new method is presented to extract quantitative information of vibration objects by using phase-stopping stroboscopic digital speckle pattern interferometry (DSPI), and it has been proved powerful. An automated analysis system is introduced. The effects of system parameters on measuring results are discussed.
