ULTRASOUND INSPECTION DEVICE AND ULTRASOUND INSPECTION METHOD

摘要

Distance measurement ultrasonic sensors (7a, 7b) for detecting the distance to the surface of a target of inspection (1) and the inclination with respect to the surface of the target of inspection (1) are provided on an ultrasonic transducer (5). An ultrasound inspection device is configured such that the distance and inclination of the ultrasonic transducer (5) with respect to the target of inspection (1) is controlled based on the information detected by the distance measurement ultrasonic sensors (7a, 7b), and such that at least one portion of the ultrasonic transmission and reception by the distance measurement ultrasonic sensors (7a, 7b) is performed during aperture synthesis processing that the transmission and reception of the ultrasonic transducer (5) do not perform.
