Abstract
A scan head includes an eddy current probe and a thermal print head. A sheet of thermal paper is mounted to the top of a laminated part being inspected and the scan head is moved across the surface of the part. A map of defect markings will appear on the thermal paper in a 1-to-1 relationship with the actual sub-surface defects. This greatly expedites the inspection process since the mapped defects are in spatial correspondence with the actual part.
