摘要
介绍了超声检测技术的最新进展,包括非接触超声检测方法、信号处理方法和模式识别技术在超声检测上的应用、研究热点和发展前景,对不同非接触超声检测方法进行了比较。超声检测新技术的出现,使得超声检测中定性、定位和定量的可靠性得到提高,也使在高温和复杂结构中的超声检测变成现实。
Some recent development of ultrasonic testing, such as the application, research status and development trend of non-contact acoustic transducer was introduced, and its advantages and disadvantages were reviewed. Also, the signal processing method and model identification were described, which could improve the location accuracy and inspection reliability. Those new method and technology could solve some difficulties confronted while inspecting in conditions of high temperature and complicated structure.
