Abstract
Techniques for detecting defects in the proximity of a hole of a laminate structure include inserting a generally cylindrical body portion into a hole such that a first coil of wire will reside in a plane substantially parallel to a first electrically conductive layer of the laminate material. A magnetic field produced by the first coil of wire will produce eddy-currents in the conductive layer in the plane of the first conductive layer, but damaged laminate materials will fail to produce similar eddy-currents. As the differences in eddy-currents between damages and undamaged laminate layers can be measured, damage to such laminate materials can be determined.
