Title: Ultrasonic wave probe
Inventor: KAWABATA KATSUYUKI
IPC: G01N29/24
Filed: 1992-11-11
Abstract: PURPOSE:To exclude the inhibition of the detection of the reflected wave from the defect of a material under test based on the reflected echo completely in a concentration type ultrasonic wave probe. CONSTITUTION:The surface 10 of an ultrasonic wave probe 1 has a transmitting region 11 which exclusively transmits ultrasonic waves, and a receiving region 12 which exclusively receives ultrasonic waves. The transmitting region 11 is located at the approximately central part of the surface 10 of the probe 1. The receiving region 12 is located at the outer periphery in a ring shape the cencer of which is the transmitting region 11. An ultrasonic-wave intercepting means 13 is adequately provided at the boundary part between the transmitting region 11 and the receiving region 12 so that the ultrasonic wave from the transmitting region 11 is not directly propagated into the receiving region 12. Therefore, the central part of the surface 10 of the probe 1 which receives the effect of the reflected echo does not receive ultrasonic waves. The reflected wave from the defect of the material under test can be definitely discriminated based on the surface echo. The direct propagation of the ultrasonic wave does not occur between the transmitting region 11 and the receiving region 12 of the ultrasonic wave owing to the intercepting means 13.
