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.
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。
