Abstract
A rotatable aperture is positioned between the pre-polygon cross-scan cylindrical optical element and the rotating polygon mirror of a laser diode flying spot raster scanner optical system. Rotating the aperture about a line parallel to the axis in the scan plane adjusts the cross-scan resolution of the imaged spot size along the scan line of the raster output scanner optical system.
