Abstract
This paper presents the characterization of defects on rivets using an eddy current based measurement system and signal processing algorithms to increase the signal to noise ratio. The instrument includes a planar eddy-current probe having a giant magnetoresistor (GMR) based sensor. The characterization of surface and sub-surface defects is depicted and the metrological performance analyzed.
