Abstract

For any given thermal imager, a pulsed temporal pattern exists that will give a higher probability of detection than any other stimulation. This paper investigates different temporal patterns that best fit the thermal properties and thickness of the materials under test, such as pulse width, pulse rate, and intensity modulation, as well as the IR equipment. An experimental analysis of the thermal inspection of composite and metal structures is presented.
