Abstract
An image compensated multi-beam system includes a beam splitter configured to receive an input light beam and split the input light beam into a plurality of processing light beams, beam scanning optics configured to receive the plurality of processing light beams and to scan the beams at a target, and an image compensation subsystem configured to selectively adjust the rotation of an image of the plurality of processing light beams at the target. A method for compensating a multi-beam image includes splitting an input light beam into a plurality of processing light beams with a beam splitter, scanning the plurality of processing light beams across a target with beam scanning optics, and selectively adjusting the rotation of an image of the plurality of processing light beams at the target.
