An eddy current flaw detection system includes an eddy current flaw detection probe having a substrate facing an inspection surface, and at least one exciting coil and at least two detecting coils provided on the substrate, a scanning device which scans the probe on the inspection surface, a scan control device which drives and controls the scanning device, an eddy current flaw detection device which acquires results of detection of a plurality of detection points corresponding to combinations of the exciting and detecting coils for each scan position of the probe, and a data processing/display device which processes data from the scan control device and the eddy current flaw detection device and thereby displays a result of flaw detection. The data processing/display device acquires three-dimensional coordinates of the detection points for each scan position of the probe and thereby creates three-dimensional flaw detection data.

Eddy current flaw detection system and eddy current flaw detection method

In an ultrasonic inspection method or ultrasonic inspection system in which an ultrasonic wave is propagated to an test object via a medium such as a liquid or a gas, an incident position of the ultrasonic wave is accurately and reliably identified. In an ultrasonic inspection method based on an immersion technique, an optical irradiator is mounted on an ultrasonic wave transmitting/receiving unit, an optical marker is irradiated from the optical irradiator to the test object, and an irradiated position of the optical marker is imaged using imaging equipment in order to perform inspection.
