Document Type and Number:
WIPO Patent Application WO/2019/150953
Kind Code:
A1
Abstract:
This ultrasonic probe: holds a transmitting transducer at an angle at which a longitudinal wave transmitted from the transmitting transducer enters an object under inspection as a transverse wave, and at which a creeping wave which propagates along a surface region of the object under inspection is generated when the transverse wave enters; holds a first receiving transducer at an angle enabling the first receiving transducer to receive a reflected ultrasonic wave generated by the transverse wave that is propagating through the object under inspection being reflected from a defect inside the object under inspection; and holds a second receiving transducer at an angle enabling the second receiving transducer to receive a reflected creeping wave generated by the creeping wave being reflected from a defect at the surface of the object under inspection.
