摘要
本文提出一种简易的用于激光全息无损检测定量判读缺陷的方法——坐标影像法。论述了该方法的原理、实验过程及结果分析。实践证明,此方法具有简便易行、造价低、准确直观的优点,为激光全息无损检测在一定范围用于在线检测提供了一种有效方法。
The coordinate shadowgraph method——a new quantitative analysis method for HNDT is presented in this article. The principle, processing and its results are discussed. The experiments prove that this method characterized by its simplicity, low-cost, accuracy and re- liability,can made the HNDT method be used in production line within certain range.
