Abstract
An inspection apparatus inspects a pressure vessel using laser ultrasound. The apparatus includes an oscillation device that oscillates an excitation laser for exciting the pressure vessel and a conduit to guide the excitation laser oscillated from the oscillation device to inside the pressure vessel. The conduit is inserted into the pressure vessel with one conduit end located inside the pressure vessel and an opposite end located outside the pressure vessel. The apparatus includes a reflector at one conduit end inside the pressure vessel to reflect the excitation laser guided by the conduit and a detector that detects ultrasonic waves generated in the pressure vessel by the excitation laser reflected by the reflector by oscillating a receiving laser from outside of the pressure vessel. At least the conduit, reflector, or detector moves to correct an optical path of the excitation laser or the receiving laser.
