Multi spi resolution flying spot raster scanner.

摘要

A rotatable aperture (24) is positioned between the pre-polygon cross-scan cylindrical optical element (20) and the rotating polygon mirror (30) of a laser diode flying spot raster scanner optical system. Rotating the aperture (24) about a line parallel to the axis in the scan or tangential plane adjusts the cross-scan resolution of the imaged spot size along the scan line (48) of the raster output scanner optical system.
