Patent number: 8085289Abstract: An optical beam is selectively output towards a scanner in accordance with image data for a scan line of an image. The optical beam has a beam irradiance distribution that is elliptical in shape. The optical beam passes through an aperture stop, ordinarily creating side lobes within a focus irradiance distribution of the optical beam. The scanner scans the optical beam to form the scan line on a photosensitive surface by selectively exposing positions along the scan line in accordance with image data. The optical beam is modified before it reaches the photosensitive surface to substantially remove the side lobes that have been created within the focus irradiance distribution and/or to substantially prevent the side lobes from being created within the focus irradiance distribution of the optical beam.Type: GrantFiled: October 24, 2008Date of Patent: December 27, 2011Assignee: Hewlett-Packard Development Company, L.P.Inventors: Dror Kella, Michael Plotkin, Shai Emanueli, Boris Aptekar, Haim Livne, Haim Vladomirski, David Kenney Towner
