ABSTRACT:
A scanner, especially one for the detection of one- and/or two-dimensional codes with a reception optics, projects the image of a reading line onto a linear arrangement of photoreceivers. An illumination arrangement for linearly illuminating an entire reading line has several substantially point-like light sources arranged adjacent to each other in a line. To boost the efficiency of the illumination arrangement, it has at least one anamorphotic illumination optics which forms the light emitted by the light sources into an illumination line.
