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.

摘要： In one embodiment, a laser peening apparatus includes an output unit (41) configured to output laser light (6); a light-guide unit (31) configured to guide the outputted laser light (6); a condenser lens (42) configured to condense the guided laser light (6); an irradiation nozzle (32) configured to radiate the condensed laser light (6); a focus-change unit (50) configured to change a focal position of the laser light (6) based on distance from an irradiation target (4, 5) of the laser light (6) to the irradiation nozzle (32); and a control unit (66) configured to apply laser peening by radiating the laser light (6) toward the irradiation target (4, 5) which is in contact with water.

摘要： A laser irradiation device comprises a laser oscillator, a laser irradiation head that performs laser processing by directing the laser beam onto the region to be processed; and a transmission mechanism that gets the laser beam through emitted from the laser oscillator to the laser irradiation head. The laser irradiation head comprises: a laser beam adjustment unit that adjusts the laser light to create a laser beam; a protective glass window arranged in an emission region that emits the laser beam; a reflection mechanism that gets the laser beam through 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; an image adjustment lens unit that adjusts an image comprising visible light that is input from the wavelength-dependent optical screening mechanism; an image pickup camera that inputs an image; and an image processing mechanism that processes the image.
