| Abstract: | The principle of measuring the self-height of cylindrical hole defect by ultrasonic tip diffraction technique was analyzed based on the characteristics of reflected and diffracted waves. The testing conditions and methods were discussed with examples. The measuring error of the method was <1mm, and it could meet the needs of practical application. |
