Ultrasonic inspection instrument

摘要

The present invention relates to an ultrasonic inspection instrument comprising:
an array sensor (14, 55) having both a transmitter element array (15) in which a plurality of transmitter elements for transmitting ultrasonic waves (16) are arrayed, and a receiver element array (19) in which a plurality of receiver elements for receiving ultrasonic waves (18) are arrayed,
a control unit (3, 7) for focusing ultrasonic waves (16) transmitted from the transmitter elements respectively on a focus point (17) where half the sum of the transmitting angle and the receiving angle will be not larger than 30 degrees,
a generation unit (4) for generating inspection information based on the ultrasonic waves (18) received by the receiver elements, and
a display unit (6) for displaying the inspection information generated by the generation unit (4) .
