Patent ID: 8481886

Claim:
A laser scanner system for removing a coating from a surface, comprising: (a) at least one laser source, wherein the at least one laser source is operative to generate at least one laser beam; (b) at least one focusing optic, wherein the at least one focusing optic is operative to receive, focus and re-direct the at least one laser beam; (c) at least one rotating multi-faceted mirror for receiving and reflecting the focused laser beam, wherein the rotating multi-faceted mirror is operative to repeatedly translate the reflected focused laser beam in one direction along an arc path and through a first focal point, and wherein passage of the laser beam through the first focal point results in divergence of the laser beam; (d) at least one reimaging mirror for receiving and reflecting the divergent laser beam toward a work surface, wherein the reimaging mirror is operative to produce an image of the first focal point and its path; and (e) wherein the at least one rotating multi-faceted mirror and the at least one reimaging mirror cooperate to produce a beam cross-over region having a minimal cross-sectional area relative to other points along the beam path, and wherein the beam cross-over region is located between the reimaging mirror and the work surface.
