Abstract
A system and method are disclosed for enhancing pit detection and sizing in a test object. Response signatures are created and stored in a signature library to characterize various sensor responses (liftoff, orientation) and pit properties (e.g., depth, width), possibly with or without additional considerations (e.g., edges, cracks). A sensor is placed on and scanned across a surface of interest on the test object. During scanning the sensor is measured repeatedly at regular intervals. An encoder may be used to record the sensor position for each measurement. The measurement results are then correlated with one or more signatures in the signature library. A threshold is used to determine if the correlation is indicative of the detection of a pit. If so additional processing may be performed to estimate pit properties.
