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： An optical scanning system is provided for producing a signal representative of a spatial distribution of indicia having different degrees of reflectivity to light, such as a bar code (14). The system includes an optical scanner (12) for scanning beam of light over the spatial distribution of indicia (14) and for producing an electrical signal corresponding to changes in the degree of reflectivity of the indicia. A digitizer (20), responsive to detections in a predetermined characteristic of the produced electrical signal is provided. The digitizer (20) converts the detections into digital words, such digital signals having a plurality of bits. The digitizer includes a timing generation circuit (42) for producing a pulse in response to each one of the detections with a time duration representative of the degree of reflectivity of the indicia as the beam of light. A decoder converts the time duration of the pulse into the digital word having a plurality of bits. An enhancement filter (30) is also disclosed. The enhancement filter (30) modifies pulses produced by a differentiator circuit (24) used in the scanner. Such modification includes increasing the rise time, and peak level of, the pulses produced by the differentiator circuit (24).

摘要： A circuit for digitizing an analog signal generated from a photoelectric conversion of reflected light when scanning indicia having spatially-separated, light-reflective portions bounded by edges includes a differentiator for differentiating the analog signal to generate a first derivative signal of the analog signal. An inverter inverts the first derivative signal to generate an inverted signal and a peak detector detects amplitude peaks of the first derivative signal and the inverted signal and generates a first peak signal corresponding to the first derivative signal and a second peak signal corresponding to the inverted signal. An adder sums the first peak signal and the first derivative signal to generate a first sum signal. The adder also sums the second peak signal and the inverted signal to generate a second sum signal. A comparator compares the first sum signal with the inverted signal and compares the second sum signal with the first derivative signal to generate pulse signals indicative of the edges of the analog signal. A controller, in response to the pulse signals, generates a digital signal corresponding to the indicia being scanned.

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： A laser focus control system including a laser for generating a scanning light beam to visually illuminate an information encoded bar code symbol. A segmented photodiode detects light reflected from the symbol and generates a plurality of electrical signals, each signal based on the light energy incident on the segments of the photodiode, thereby representing the spatial intensity variations of the symbol. A scanning zone processor then filters, averages, and compares the electrical signals to a noise threshold, and assigns logic levels based on the comparisons. Thereafter, a scanning zone detector determines the corresponding scanning zone distance based on the combination of logic levels and determines whether the system has stabilized within the zone distance. The scanning zone distance is then furnished to the laser focus controller in order to adjust the laser focus of the scanning device. The system is incorporated in a shock-resistant hand-held device.

摘要： A circuit for digitizing an analog signal generated from a photoelectric conversion of reflected light when scanning indicia having spatially-separated, light-reflective portions bounded by edges includes a differentiator for differentiating the analog signal. An inverter inverts the differentiated signal to generate an inverted signal. A negative peak detector detects negative amplitude peaks and a positive peak detector detects positive amplitude peaks of the differentiated signal and generate, respectively, a negative and positive peak signal. Adders are used to add the positive peak signal to the inverted signal, and the negative peak signal to the inverted signal. A comparator compares the two summed signals to the differentiated signal and generates pulse signals indicative of the edges of the analog signal. A controller, in response to the pulse signals, generates a digital signal corresponding to the indicia being scanned.

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.
