用全息横向错位法判别物体变形方向
Determination of the Direction of Deformation on Surface by Lateral Shearing Holographic Interferometry
-
摘要: 本文提出了利用干版横向错位法来判别物体表面变形方向的原理,分析了干版移动方向与干涉条纹变化之关系,并用实验结果加以验证。Abstract: In this paper a principle for determining the direction of deformation on surface by lateral shearing holographic interferometry is proposed and the relationship between the direction of movement of holographic plate and the change of interferometric fringes is discussed. The principle is verified by means of experimental results.
