Abstract
Disclosed is a system and method for patterning internal and/or external doubly-curved surfaces by use of a light source, three-dimensional scanning optics, computer controller, and a multi-axis robot. The system is capable of digitally receiving shape, location, and pattern data of a three-dimensional doubly-curved surface and applying said pattern over large areas with high precision in a seamless fashion.
Claims20
A method of forming a pattern on a doubly-curved surface comprising:
- (a) providing a substrate having a doubly-curved surface mounted for rotation about an axis of the substrate;
- (b) providing an optical system in relation to the substrate, the optical system operative for projecting a focal point of light to different points of the doubly-curved surface that are different distances from focusing optics of the optical system;
- and
- (c) under the control of a software controlled computer controller, rotating the substrate about its axis in coordination with the operation of the optical system to move the focal point of light in a pattern on the doubly-curved surface.

A method of forming a pattern on a doubly-curved surface comprising:
- (a) causing a focal point of a light beam to appear at a first point on a doubly-curved surface;
- (b) changing a focal length of the light beam in step (a);
- and
- (c) causing the focal point of the light beam changed in step (b) to appear at a second point on the doubly-curved surface.
