Paper Abstract

A thermal projector design is discussed as implemented to perform forced diffusion thermography. The system projects a continuous dynamic pattern of heat in order to drive thermal conduction across flaws. The simple projector utilizes a conventional 625 watt incandescent source and a servo-controlled mirror system to create a simple moving line pattern of heat. Although the system is capable of detecting a variety of flaws, it is most suited for crack detection. Projector design and results are presented.
