Description

Since its introduction several years ago, the self-nulling eddy current probe [1–3] technology has been one of the focal points of the aging aircraft related R&D effort. Numerous application areas have broadened the scope of the probe which has also helped in better understanding the underlying principle. As the technology matures, however, deeper understanding on the various details related to the self nulling effect is needed to overcome difficulties associated with the current field tests and expand its application areas. A particular problem to be addressed is in differentiating the effect of small, shallow surface cracks from that of probe wobble during automated data acquisition operation.
