ABSTRACT:
Systems and methods are described that dynamically correct field curvature and other focus errors in imaging systems that use rotating scanners to scan an image field. The dynamic correction controls the focusing of an image field such that focus is maintained across the width of a photosensitive element as a rotating scanner scans the field. The described systems and methods enable the use of post-objective scanning configurations in which the complexity and expense of objective lenses is significantly reduced.
