目前用储光全息干涉测量法对普通表面的变形进行实时差示测量,其精度大约可达百万分之一时。本文介绍了在技术上切实可行的几种试验,还介绍了一些对连接组件和其它构件进行非破坏性试验的全息干涉测量法进行鉴定的几种试验。在一些试验中引用了能自己显影的光色材料,以缩短试验的时间,降低试验的复杂性和费用。本文附有表明粘合剂粘结的缺陷位置和结构裂缝位置的干涉图样,以说明迄今已探讨过的领域中,全息干涉测量法成功地用于非破坏性试验中的情况。
At present, the holographic interferometric measurement method is used for real-time differential measurement of the general surface deformation, and the accuracy is about one millionth of an hour. This article describes several technically feasible tests and describes several tests for the identification of holographic interferometry for non-destructive testing of connected components and other components. In some experiments, self-developing photochromic materials were cited to shorten the test time and reduce the complexity and cost of the test. This article is accompanied by an interference pattern indicating the location of defects and the location of structural cracks in the bond of the adhesive to illustrate the successful application of holographic interferometry to non-destructive testing in the field explored to date.
