摘要： A system for detecting voids or imperfections such as holidays in a coating having fluorescent material therein comprises a camera having a digital image output for inspecting the coating wherein said camera's digital image output may include only the image produced by light in a color spectrum corresponding to a portion of the spectrum of light produced by fluorescent emission of the coating, thereby revealing the presence of any imperfections. Furthermore, an ultraviolet light source is provided to illuminate the coating and excite fluorescent emission therein. In one embodiment, the system is capable of distinguishing between an imperfection and the complete absence of a substrate surface. The system is also capable of revealing coating defects or imperfections in irregular surfaces. A microcontroller is also provided, having an associated memory, an input for accepting the digital image output from the camera, and an output representative of an analyzed digital image wherein said analyzed digital image includes visible indicia of any voids or imperfections detected in the coating.
