Paper Abstract

MR sensors offer a significant increase in sensitivity for inspection of subsurface features and flaws in metallic aircraft structure. This is especially true for deeper inspections with depths between 10 and 20 mm below the accessible surface. I show C-scan images of deep flaws, with dimensions down to one-tenth of the thickness of the covering metal. Issues involved in developing and operating an imaging scanner using these sensors are discussed.
