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.
