Eddy Current Probe Performance Characterization
Single-coil, absolute eddy current probes are used extensively by the Air Force for inspection of aluminum airframe structures. Because of the large variations in probe performance , a specification is needed to ensure that probes meet minimum performance criteria. In order to develop these criteria for the specification, it was necessary to assess the probe performance factors that limit flaw detectability and then to determine the response of typical probes used by the Air Force so that reasonable thresholds can be established without rejecting a large number of probes.
