Abstract

Digital speckle photography combined with TV shearography is developed for precise measurement of the magnitude of the shear field in a linear shear configuration. As an application the method is implemented to determine the slope-change variations of a three-dimensional object with TV shearography in which the shear magnitude is obtained with the digital speckle photography technique.

摘要

数字散斑摄影与电视剪切术相结合,用于精确测量线性剪切配置中剪切场的大小。作为一种应用,该方法被用于通过电视剪切术确定三维物体的斜率变化,其中剪切大小是用数字散斑摄影技术获得的。
