摘要： A miniature imager for reading target images. The optical and electrical systems of the miniature imager are optimized to reduce one or more dimensions or the volume of the imager. In accordance with one embodiment the pixel pitch and focal length are decreased for that of a larger imager to maintain a comparable field of view for each pixel. The decreased pixel pitch allows the area of the aperture and the instantaneous field of view of the pixel to remain constant while decreasing the overall size of the imager. In other embodiments apparatus and techniques reduce and/or eliminate the need for illumination of a target by the imager thereby reducing the overall power consumed by the imager and/or its overall size. The imager has an increased working range.

摘要： An optical code reader is provided including imaging circuitry having an array of photo sensing devices capable of sensing light incident on the array and outputting a plurality of pixel signals corresponding to the sensed light. The reader further includes control and logic circuitry for receiving a subset of the plurality of pixel signals, processing the received subset of the plurality of pixel signals for determining if the received pixel signals meet at least one predetermined condition, and outputting a selection control signal in accordance with the processing results.

A selector control software module executable by the control and logic circuitry generates a selection control signal in accordance with the determined focus quality of the received pixel signals. Selector circuitry selectively enables the imaging circuitry to output selected pixel signals of the plurality of pixel signals in accordance with the selection control signal.

摘要： 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, 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.
