Abstract:
1. A system for generating a laser machined tool, comprising: a laser producing a laser beam image; a substantially cylindrical work piece, wherein the system is capable of rotating the work piece; and an optical system for processing the laser beam image and for imaging the processed laser beam image onto a convex outer surface of the work piece, wherein the processing of the laser beam image is related to a curvature of the outer surface of the work piece, and the processing generates a cylindrical image plane from the laser beam image with the principal rays of the laser beam image in the cylindrical image plane being substantially perpendicular to the convex outer surface of the work piece, and wherein the laser beam image is capable of ablating the convex outer surface of the work piece in order to create microstructures within the surface to form a substantially cylindrical tool.
