Abstract
A pulsed heat energized system for detecting corrosion or similar oxidation products located intermediate a layer of metal and an overlying layer of paint or other metal protective material. The system employs a continuing stream of radiant thermal energy pulses impinging on the external surface of the coated metal and responds to the phase angle difference between a waveform representing the energy pulses and a waveform representing the undulating temperature response of the paint surface to the energy pulses. Use of the system for detecting corrosion of a military or other aircraft in order to avoid stripping the aircraft for corrosion inspection and correction is contemplated. Enhanced independence of the corrosion detection from measurement variations and earlier detection of corrosion presence are achieved with respect to other corrosion arrangements.
