Abstract:
1. An eddy current probe for inspecting a structure comprising: a plurality of first coils oriented in a first direction; an alternating current source electrically connected to respective ones of the plurality of first coils; a plurality of second coils oriented in a second direction, different than the first direction, such that the plurality of second coils cross the plurality of first coils to define respective sensing elements, wherein each of the first and second coils is elongated, wherein each first coil defines a first major axis extending in the first direction, wherein each second coil defines a second major axis extending in the second direction, and wherein said first and second coils comprise a plurality of turns of a conductive member; and sense electronics for sensing current induced in respective ones of the plurality of second coils, wherein the current sensed in a respective second coil is representative of at least one characteristic of the structure proximate the corresponding sensing element.
