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 on a focus point (17),
an amplification control unit (3, 9, 10) for changing the amplification of a signal to be supplied to each of the transmitter elements and/or the amplification of a signal to be supplied from each of the receiver elements, in accordance with the focus point (17),
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).
