摘要
本文叙述应用电子错位散斑干涉仪于各种缺陷的无损检测的装置原理、各种加载方式的特点.文中详细探讨了缺陷检测定量分析的理论依据,提出了对各种不同材料缺陷检测的限制并进行了实验验证;提出了提高条纹清晰度的方法.从而解决了电子错位散斑干涉术在无损检测实际应用中的各项具体问题.
The principle and loading device of electronic shearing speckle interferometer for NDT(nondestructive testing)are described.The theoretical background of quantitative analysis for NDT is studied in detail.Limitations of NDT for different materials are presented and veri- fied experimently.Some methods for improving fringe quality are also proposed.
