摘要： A multiple working range scanner includes a collection mirror which is segmented, with each segment having differing optical properties, such as focal length, optical axis, and so on. Differing segments or combinations of segments deal with reflected light received at differing working ranges, and direct it to a photodetector. In another embodiment, beam shaping may be applied to an astigmatic laser beam, for example by means of a part-concave mirror, to create an x waist in the beam which is further from the scanner than the y waist. This provides enhanced performance when the scanner is used on a bar code symbol which is not accurately aligned. In order to provide improved optical alignment within a bar code scanner, the collection mirror may be adjustable both in the x direction and in the y direction.

摘要： An optical scan module, for example for an optical scanner, includes an integrally molded plastics material member which defines not only the laser focusing lens, but also the laser focusing aperture and the collection mirror. In addition, the molded member may act to house and to locate both a semiconductor laser and a photodetector, thereby ensuring easy and accurate placement of those elements within the scanning assembly. The optical assembly may be in modular form, mounted onto a common printed circuit board with a beam scanner.

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.

摘要： A scanner determines whether a target is a bar code symbol and, if so, whether that symbol is one-dimensional or two-dimensional. For two-dimensional symbols, the scanner aligns a scanning pattern with the symbol and expands the scanning pattern to reach only to the top and bottom edges of the symbol, not beyond. The scanner also has a microprocessor-control scanning engine that uses a coil to drive a scanning element and pick up feed back signals from the scanning element. A pulse-width-modulated regulator also provides fast and efficient operation for driving the coil. The scanning engine can also be designed to generate a pattern that precesses across the target, and a powerful interface to the scanning engine allows decoding and control logic to work efficiently with and independently of the scan engine.
