  • Publication number: 20180217099
    Abstract: Disclosed is an apparatus and method for generating virtual inspection channels mid-way between the physical inspection channels of an eddy current array probe, thereby reducing the coverage loss and improving defect sizing and imaging. The method is based upon a calibration to determine the mid-channel coverage loss for parallel defects having their long axis parallel to the scanning direction. Based on the coverage loss measurement, a vector analysis system is constructed enabling generation of virtual channel signals which are available for processing in the same way as physical channels, with impedance plane representation including real and/or imaginary signal components. The system differentiates between parallel and perpendicular defects and employs different algorithms to generate virtual channel signals for parallel and perpendicular defect orientations.
