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.

Abstract: The disclosure relates to systems and techniques for reading optical codes, and more particularly to code reading systems with plural imaging or scanning modules pointed in various directions toward a target volume, which increase the likelihood that a code symbol on an arbitrarily oriented object in the target volume will be read. Other aspects of the invention relate to use and configuration of hand held readers, docking devices, operator side rails, arched tunnels and mirrors for increasing the coverage of the system. Additional aspects of the invention relate to components associated with point of sale installations or code reading terminals including integrated scales, input pads, system controls and displays.

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 imaging lens assembly focuses light from indicia in a working range of distances along an optical path onto a solid-state imager of an imaging reader. The lens assembly includes a negative spherical aberration component and an aperture stop that together are operative for extending the working range.

Abstract: A method of operating a laser scanner for reading a barcode. The laser scanner is configured to operate in at least two operating modes including a scanning mode and an aiming mode. The method includes operating the laser scanner in the scanning mode after a trigger signal is generated by a trigger on the laser scanner, and decoding the electrical signal that is received from the photodetector when the laser scanner is in the scanning mode. If the electrical signal from the photodetector is not successfully decoded after a first predetermined time period since the trigger signal is generated, alternating the laser scanner between the aiming mode and the scanning mode.
