Patent ID: 8276452

Claim:
An ultrasonic inspection apparatus comprising: a laser apparatus that irradiates laser light; a plurality of ultrasonic wave transmitting portions each having a first diaphragm that is irradiated by the laser light emitted by the laser apparatus and that generates ultrasonic waves; a plurality of ultrasonic wave receiving portions each having a second diaphragm that vibrates due to receiving the ultrasonic waves that have been reflected from an inspected object and a laser member that emits a laser light to the second diaphragm and receives laser light that has been reflected from the second diaphragm; and a probe, wherein the laser apparatus includes an intensity adjusting means, which adjusts a frequency and an intensity of the ultrasonic waves generated by the first diaphragm with adjusting the intensity of the laser light incident to the first diaphragm; the plurality of the ultrasonic wave transmitting portions are configured so as to generate ultrasonic waves having different frequencies; the plurality of the ultrasonic wave transmitting portions and the plurality of the ultrasonic wave receiving portions are integrally supported with the probe; the probe includes a main body which is a box, and a passage portion through which an optical fiber is passed; the first diaphragm of the plurality of the ultrasonic wave transmitting portions and the second diaphragm of the plurality of the ultrasonic wave receiving portions are arranged so as to face a surface that is opposed to the passage portion of the main body; and the ultrasonic inspection apparatus carries out inspections by irradiating the ultrasonic waves that are generated by the first diaphragm of the plurality of the ultrasonic wave transmitting portion to the inspected object.
