The Newly Research and Application of Ultrasonic Testing Technique

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.
