Description

Current practice in the design of eddy current probes calls for an optimum balance between detection sensitivity and false rejection of test pieces. Naturally, designers have emphasized improving the sensitivity and signal-to-noise ratio of eddy current probes to achieve these goals. As progress has been made in mathematical modeling of eddy current flaw signals, it has become possible to consider designing probes for specific functions and workpieces. It is now recognized that probes of different design might be required for detection and inversion. The study described here is one of the first instances in which an eddy current probe was designed specifically for inversion. This has involved balancing an entirely different set of constraints than those that must be optimized for a probe intended for detecting flaws.
