Abstract
In the study of the deformation of objects by holographical interferometry, it is possible to determine directly strain components by measurement of the contrast of the fringes. With adequate geometry and a zero method, contrast measurements give accurate values of the strain components.
摘要
在通过全息干涉测量法研究物体变形时，可以通过测量条纹的对比度直接确定应变分量。采用适当的几何结构和零值法，对比度测量可得出应变分量的准确值。
