Abstract
A coating removal apparatus removes a coating from a surface. The apparatus has a movable scanning head and scanning optics. The scanning head is movable in one dimension, and the scanning optics adjust in two dimensions to compensate for movement of the scanning head to implement long range scanning with a uniform scanning pattern. Further, a surface roughness is determined by measuring specular and scattered reflections at various angles. For composite surfaces, the apparatus utilizes UV laser radiation and a controlled atmosphere to remove coating and alter the chemical characteristics at the surface.
