【摘要】 采用瞬态光学图像采集技术，实现了动态数字散斑干涉（ＤＳＰＩ）．以周边固支圆板受法向撞击集中载荷为例，对其离面位移场进行了测试．实验值与动有限元计算结果比较，两者是比较接近的更多还原

【Abstract】 The dynamic digital speckle pattern interferometry(DSPI) has been achieved by using the instantaneous image capturing technique. The measurement of out of plane displacement field of circular restrained plate with a cross point impact loading is completed. The results of dynamic finite element method show good agreement with those of experiments.更多还原
