A device for inspecting a component

A device for inspecting a component includes an eddy current array circuit having respective pluralities of drive and sense elements and having an active face for positioning on a surface of the component during the inspection operation. A backing is disposed on a face of the eddy current array circuit opposite to the active face for concentrating an electromagnetic flux from the eddy current array circuit into the component when each of the plurality of drive elements is being energized. In accordance with one embodiment of the present invention, a core member supports and deploys the backing and the array circuit to substantially conform to the surface portion of the component under inspection and to cause each of the respective pluralities of drive and sense elements to remain at a respective substantially constant distance from the component surface portion during scanning by the device to detect defects within the component. In another embodiment of the present invention, a mechanical arrangement is provided for supporting and deploying the backing and the array circuit to substantially conform with the surface portion under inspection and to cause each of the pluralities of drive and sense elements to be maintained at their respective substantially constant distances from the inspection surface during scanning, preferably at a controlled rate of scan.
