A system employing thermographic techniques is provided for inspecting materials and detecting defects therein such as void, inclusions, interlaminar disbonds, or porosity. The system utilizes a composite material and a source of pulsed current which is delivered to conductive elements within the composite material which, in turn, heats the material being inspected allowing thermographic techniques to be employed to measure the temperature distributions related to the application of the heat source and indicative of the defects of the material being measured.
