Conventional eddy current technology has been used for many years to inspect the surfaces and subsurfaces of various components across a wide range of industries. This electromagnetic technique can reliably detect surface-breaking flaws, such as cracks, and subsurface defects, such as corrosion. Unfortunately, inspecting large surface areas using a single-coil probe is extremely impractical as the process would be too time consuming and the probability for missed flaws too great. Eddy current array (ECA) technology remedies these issues. Furthermore, the capacity of ECA to inspect large surfaces makes it an advantageous replacement for traditional techniques such as magnetic particle or liquid penetrant inspection.
