Abstract: Devices and methods for detecting defects in reinforced concrete using eddy current detection technology are disclosed. In one aspect, a method for detecting defects in reinforced concrete may include the steps of: providing a probe with a plurality of eddy current sensors disposed along a circumferential direction of the probe; inducing an eddy current in a reinforcing structure of the reinforced concrete with at least one of the plurality of eddy current sensors; and detecting a circumferential and longitudinal location of a defect in the reinforcing structure of the reinforced concrete with at least one of the plurality of eddy current sensors.

Abstract: Eddy current detection probes and related methods are disclosed. In some embodiments, the eddy current detection probes are hybrid probes, including a solid state sensor and a detection loop. In some embodiments, the eddy current detection probes include a drive coil and a detection loop, with the detection loop having a sensitive axis that is not parallel to principal axis of the drive coil. In some such embodiments, the sensitive axis of the detection loop is perpendicular to the principal axis of the drive coil.
