摘要： A laser irradiation device in which laser light is adjusted to create a laser beam, including a protective glass window arranged in an emission region that emits the laser beam; a reflection mechanism that passes the laser beam and reflects visible light; a wavelength-dependent optical screening mechanism that cuts off light of a wavelength region other than visible light from the light that is reflected by the reflection mechanism; image pickup camera configured to capture the visible light reflected with the reflection optical element; and an image adjustment lens unit that adjusts an image in the visible light that is input from the wavelength-dependent optical screening mechanism. The wavelength-dependent optical screening mechanism is provided between the reflection optical element and the image camera.

摘要： An eddy-current flaw detector includes a trace data calculator configured to calculate each coordinate with respect to flaw detection points on which an inspection probe is used upon performing an eddy-current testing based on an inputted condition of eddy-current flaw detection and surface shape data of an inspection-object surface measured by a profilometer, and to calculate a normal vector of each flaw detection point; a gap evaluation calculator configured to acquire an evaluation result on a gap between the inspection-object surface and the inspection probe for each flaw detection point; a flaw detection data collector configured to acquire flaw detection data of an inspection object for each flaw detection point; a flaw detection data analyzer configured to evaluate presence/absence of a flaw in the inspection-object surface based on the flaw detection data of the inspection object and the evaluation result on the gap for each flaw detection point.
