This paper describes a moiré technique for gauging surface deformations of an object or differences in the surface configuration of two similar objects. A grid pattern is generated on the object by illuminating it with a laser interference pattern, and a master negative is made by photographing the illuminated object with a view camera. With the negative occupying its original position, the moiré pattern corresponding to changes in the object can be observed in real time by viewing the image of the deformed or second object through the negative. The technique is noncontacting and quantitative. It is useful with objects of any size, and its sensitivity can be easily adjusted to suit the application.
本文介绍了一种用于测量物体表面变形或两个相似物体表面构型差异的莫尔技术。通过用激光干涉图案照射物体，在物体上生成网格图案，并用取景相机拍摄被照射的物体制作主底片。将底片置于其原始位置，通过底片观察变形物体或第二个物体的图像，可实时观察到与物体变化相对应的莫尔图案。该技术是非接触式且定量的。它适用于任何尺寸的物体，并且其灵敏度可以很容易地调整以适应应用。
