Abstract: The invention relates to optical scanners. The invention comprises a multi-range scanner assembly for electro-optically reading indicia having parts of differing light reflectivity on a target located at a variable distance from the assembly, comprising: (a) a first light source for producing a first beam for short range scanning operations; (b) a second light source for producing a second beam for long range scanning operations; (c) a scanning element including a scanning mirror for causing the first and second beams to be alternately scanned over a field of view; (d) a collection optical system for collecting light reflected from the field of view; and (e) an optical detector for detecting light directed thereto by the collection optical system and for generating electrical signals corresponding to the reflected light.

Abstract: An optical scanner such as a bar code scanner includes a segmented fold mirror, the individual sections of which have different profiles. By directing the scanning laser beam across the fold mirror, plurality of scan lines are created, at different distances from the scanner. This provides increased flexibility by extending the scanner's working range. In alternative embodiments, a collector mirror and/or a scanning mirror may be segmented. In addition, beam shaping may be provided by reflecting the beam from one or more aplanar surfaces.

Abstract: An optical scanner such as a bar code scanner includes a segmented mirror (14), the individual sections of which have different profiles (16,18,20). By directing the scanning laser beam across the mirror, a plurality of scan lines are created, at different distances from the scanner. This provides increased flexibility by extending the scanner's working range. In alternative embodiments, a collector mirror and/or a scanning mirror may be segmented. In addition, beam shaping may be provided by reflecting the beam from one or more aplanar surfaces.
