发明名称 Closed loop focusing system
摘要 A system for focusing light including a gradient index lens array positioned at a first distance from a surface, and first and second positioning elements arranged to modify the first distance. The first and second positioning elements modify the first distance based on an analysis of an image formed on the surface across substantially a full width of a cross process direction of the surface.

主权项 1. A system for focusing light comprising: a gradient index lens array positioned at a first distance from a surface to form an image of an object onto the surface; and, first and second positioning elements, wherein the object being an array of light emitting diodes placed at a second distance from the gradient index lens array, the first distance being independent of the second distance, wherein the first and second positioning elements modify the first and/or second distance based on an analysis of the image formed on the surface across substantially a full width of a cross process direction of the surface.
