PROBLEM TO BE SOLVED: To improve the signal-to-noise ratio, and to improve detection of defects of edge, in edge flaw detections for components. SOLUTION: An eddy current (EC) probe (12) for inspecting a component (16) is provided. The EC probe includes a drive coil (30), configured to generate a probing field for inducing eddy currents (18) in the component, where a portion of the eddy currents is aligned parallel to an edge (38) of the component. The EC probe further includes a pair of sensing coils (34, 35), where the axis (50) of the sensing coils is aligned perpendicular to the surface (14) of the component. The sensing coils are configured so as to sense the portion of the eddy currents, aligned parallel to the edge of the component. COPYRIGHT: (C)2006,JPO&NCIPI
