Patent attributes
A laser-based coating removal apparatus to remove a coating from a surface without damaging the surface. The apparatus comprises a laser source to provide a laser light, a routing element coupled to the laser source and configured to direct the laser light onto a target region of the surface thereby removing the coating from the target region, and a detection element to detect the coating as the coating separates from the target region of the surface. The detection element is able to prevent the surface from being damaged by limiting or eliminating the laser light directed onto the target region after all the coating has been removed. The detection element is able to detect the separation of the coating from the target region by detecting incandescence, acoustic signature, motion, fluorescence and/or chemical properties produced by the separation of the coating from the surface.
