Abstract: A method and system for inspecting an object is provided. In accordance with embodiments of the method, a thermal excitation pulse is applied to an object undergoing evaluation. A transient thermal signal from the object is detected in response to the thermal excitation pulse. Two or more orthogonal functions are applied to the transient thermal signal based on a defined time interval to generate two or more orthogonal components. The object is assessed for defects at different depths using the two or more orthogonal components.

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.
