  • Patent number: 12140564
    Abstract: A defect detection method includes: a step of irradiating an object with a pulsed laser beam to continuously generate ultrasonic waves in the object; and a step of detecting the presence or absence of an internal defect of the object on the basis of the presence or absence of resonance of the ultrasonic waves occurring between a surface of the object and the internal defect. In this method, the internal defect is detected on the basis of the presence or absence of resonance of the ultrasonic waves occurring between the surface of the object and the internal defect. The internal defect can be thus detected even when the internal defect is in a surface layer of the object. The detected internal defect is crack or void.
