ABSTRACT:
A system for controlling satellite beams in either a tangentially or sagittally offset optical alignment of the type used with raster scanners without introducing objectionable cross scan bow to the image line wherein the axes of the input beam is set at a predetermined small angle to the scan plane axes of the scan lens and the rotating scanning element are set at a predetermined small opposing angles to one another with respect to the scan to promote divergence of any satellite beams and thereby facilitate intercepting and blocking thereof without interfering with the imaging beam, the angular relationship between the axes of the input beam and scan lens and the axis of the scanning element minimizing cross scan bow of the image line at the image plane.
