Abstract
Official abstract text for this publication.
A scanning system includes a synchronizing arrangement including a light guide and a photosensor. The light guide directs a light beam to a photosensor, wherein light is deflected by one or more moving elements in the scanning system into a scanning region. The light guide has a light entry region, a reflecting region for reflecting light entering the light entry region and one or more light exit faces, so that light entering the light guide through the light entry region is at least partly reflected in the reflecting region and exits through one of the exit faces. The shape and the properties of the light guide are such that for two pencils of light rays, a first pencil of light rays is spaced from the second pencil and is non-overlapping with said second pencil of light rays.
