Abstract: Present embodiments include eddy current array probes having differential coils capable of detecting both long and short flaws in a test specimen and, additionally or alternatively, multiplexed drive coils. For example, an eddy current array probe may include a first plurality of eddy current channels disposed in a first row and a second plurality of eddy current channels disposed in a second row. The first plurality and second plurality of eddy current channels overlap in a first direction but do not overlap in a second direction. The probe also includes a semi-circular drive coil disposed proximate to the first plurality and second plurality of eddy current channels and configured to generate a probing magnetic field for each sense coil of the eddy current channels.
