Abstract:
1. A laser-based coating removal system to remove a coating from a surface, the system comprising: a. a laser source to provide a laser pulse; b. scanning optics to direct the laser pulse along a laser path to a first position on the surface, whereby the laser pulse impinges the first position on the surface thereby ablating a portion of the coating from the first position; c. a plurality of light illuminators to provide a corresponding plurality of light illuminations, each light illumination along a light illumination path, wherein each light illuminator provides a light illumination that is temporally distinct from the light illuminations provided by each of the other plurality of light illuminators, further wherein each light illumination impinges the first position on the surface; and d. a photosensitive detector to receive light reflected from the surface as a result of the impinging light illuminations and to measure the reflected light, wherein the reflected light is directed along a plurality of color sensing paths, wherein all of each color sensing path is independent of all of each light illumination path, and wherein photosensitive detector temporally separates the reflected light resulting according to the temporally distinct light illuminations impinging the surface.
