Abstract:
1. A method of forming a dense brush of interleaved flying spots using optics that have a minimum separation distance among flying spots projected onto a workpiece that makes adjoining coherent beams non-interfering, including: forming a first brush of flying spots of coherent radiation with a first separation among the first flying spots when projected onto the workpiece that is as large as or larger than the minimum separation distance; forming a second brush of flying spots of coherent radiation with a second separation among the second flying spots when projected onto the workpiece that is as large as or larger than the minimum separation distance; and characterized by the further action of interleaving the first and second brushes of multiple coherent flying spots where the distance between individual flying spots in the first brush and individual flying spots in the second brush when projected onto the workpiece is less than the minimum separation distance, wherein the first flying spots are conditioned to not interfere with the second flying spots.
