一、概述 激光全息干涉法在机床检验与测量方面已得到了广泛的应用。用这种方法可以观测几乎任何物体表面的微小变形(静、热和动态变形),而且特别适宜于对机床的接合面特性进行研究。但由于多种原因激光全息干涉技术不宜单独使用,只能用它来补充或部分代替模态分析法。从而使机 First, an overview Laser holographic interferometry in machine tool inspection and measurement has been widely used. With this method, it is possible to observe small deformations (static, thermal and dynamic deformation) on almost any surface of an object, and is particularly suitable for studying the characteristics of the joint surface of a machine tool. However, due to various reasons, laser holographic interferometry should not be used alone, it can only be used to supplement or partially replace modal analysis. So that machine
