业已证明,全息照相干涉测量术对各种物体进行无损检验是实用的。新的光学干涉条纹扫描技术有极大希望扩大全息照相干涉测量术作为无损检验工具的能力。本文讨论了光学干涉条纹扫描技术在检验迭层结构中给与较高的分辨率,以提高探测伤痕能力的应用情况。并将声明这些新技术如何显著地提高全息照相无损检验的检验速度。另外,示出了用全息照相术对轮胎进行无损检验的某些普遍的结果。在全息照相干涉测量术的振动分析领域里已研制出一种技术,能探测出振动级为10~(-7)～10~(-8)厘米的振幅。本文将讨论这些新概念,并概述无损检验的可能性。
It has been demonstrated that holographic interferometry is useful for nondestructive testing of various objects. The new optical interference fringe scanning technology has great hope to expand the ability of holographic interferometry as a nondestructive testing tool. This article discusses the application of optical interference fringe scanning technology in the inspection of laminated structures to give higher resolution to improve the ability to detect flaws. And will state how these new technologies dramatically improve the inspection of holographic non-destructive testing. In addition, some general results of non-destructive testing of tires with holography are shown. In the field of vibration analysis of holographic interferometry, a technique has been developed that can detect vibration amplitude of 10 -7 to 10 -8 cm. This article discusses these new concepts and outlines the possibility of non-destructive testing.
