Abstract:
1. An automated inspection system for nondestructive inspection and evaluation of an electrically-conductive workpiece based on induction thermography, the system comprising: a movable carriage arranged to translate the workpiece in an inspection location; an induction coil disposed at the inspection location, the induction coil responsive to an excitation current to induce a flow of electrical current in a region of interest of the workpiece; a thermographic camera disposed at the inspection location, the thermographic camera arranged to capture data indicative of a thermal response resulting from the flow of electrical current; a reflector arranged to reflect within a field of view of the thermographic camera, data indicative of a thermal response from a portion of the workpiece that otherwise would not be captured by the thermographic camera; and a computer system configured to process the data from the thermographic camera to generate an indication of a presence of a discontinuity in the workpiece.
