Abstract
The present invention relates to a system for imaging the surface of a substrate through a coating on the substrate. The system includes an infrared light source positioned to cast an infrared light upon the substrate to thereby create reflected light. A focal plane array may be positioned to receive the reflected light and generate an image therefrom. At least one optical filter may be disposed between the substrate and the focal plane array so as to pass only coating transparent wavelengths of the reflected light along an optical path between the infrared light source and the focal plane array thereby visually revealing irregular structural features of the substrate as at least one image.
