Abstract

Scan systems include at least one radiation source for directing at least one beam toward a scan-device system. The scan device system includes at least one scan device that reflects these beams as rotating scan beams which point to the optical aperture of a rotating optical system. The rotating optical system has at least one optical component selected from a group of reflectors and lenses, focuses the scan beams into radiation spots, and projects them onto a scanned surface as moving scan spots. Linear relative movement between the scanned surface and the rotating optical system produces an area scan of inner drum or planar surface.
