Abstract
Oscillatory signal build-up is increased in the polar coordinates sensor by integrating the rotating driving flux with the resonating flux resulting from the series resonant pick-up coil current. The imbalance flux linking the pick-up coil is more dependent on radii proximate the z-axis and is more suitable for detection of cracks radial to an aircraft rivet.
