摘要： A scanning device incorporates a vertical cavity surface emitting laser (VCSEL). The laser diode may be mounted directly on an Si substrate which is adapted for movement to produce a scan pattern. A collimating lens may be directly mounted on the emitting surface of the laser. A plurality of lasers may be mounted on the substrate and operated in sequence without movement of the substrate to produce the effect of a scan. The scanning device emits visible or invisible light towards a target such as a bar code and a detector (mounted on the same or an adjacent substrate) senses the light reflected by the target to produce data which is decoded for further processing. A VCSEL uses low current and emits light from a relatively large area so that a relatively large amount of light is emitted for relatively small heat generation.

摘要： In an optical scanning module, for reading indicia with portions of differing light reflectivity, having a light emitter assembly for emitting a light beam towards the indicia, and a detector for receiving light reflected back from the indicia and producing an electrical signal corresponding to the differing light reflectivity of the indicia, an optical scan module component is provided which includes two circuits on respective circuit boards which are angularly mounted, and preferably orthogonally mounted, to each other. The two circuit boards are electrically connected to each other so as to operate together to produce signals to drive the emitter assembly and to process the electrical signal produced by the detector. The first and second circuit boards each form at least a portion of a peripheral side of the scanning module and thus, defining a wall of a chamber having the light emitter assembly disposed therein, and wherein the scanning light beam moves relative to the first and the second circuit boards.

摘要： A plurality of the areas of different light reflectivity of a bar code symbol, or the like, are simultaneously illuminated, using, e.g., a beam of laser light that has an elongated cross-section. The laser light beam is swept over the symbol in a direction transverse to the elongated dimension of the illuminated region so that a two-dimensional area of the symbol is illuminated over time, until the symbol is read. The light that reflects from the illuminated region of the symbol is imaged on a linear sensor array, which is then scanned or read out to produce signals representative of spatial intensity variations of the imaged light along a linear path in the field of view.

摘要： A scanner module for use in a bar code reader has a scanning mirror which is mounted to a bracket by way of leaf-spring, allowing the mirror to oscillate in one direction. The bracket is hung from a stationary chassis by means of two strips of mylar film, allowing the entire bracket to oscillate in the perpendicular direction, thereby providing two dimensional oscillation of the mirror and raster scanning of a light beam reflected from the mirror. The mylar sheets are protected against mechanical shock by pins which pass through holes in the bracket. The pins are slightly smaller than the holes, allowing sufficient clearance for movement of the bracket during normal operation, but preventing too much stress being placed upon the mylar films if the module is dropped. The pins also provide accurate alignment of the bracket with respect to the chassis.

The device directs a light beam toward the indicia, and collects reflected light from the indicia.

摘要： In an optical scanner, a component for producing a beam scanning motion is mounted on a first flexible strip or planar spring. One or more additional flexible strips, adjacent the first flexible strip, provide additional support to prevent droop by the first flexible strip under the weight of the scanning component. The additional flexible strips also frictionally damp the low frequency motion of the first flexible strip to prevent interference with scanning due to vibration induced from movement of the scanner by an operator. In two-dimensional scanners, where the component moves in two orthogonal directions at two different speeds, the additional strip type frictional damping is applied to the planar spring which provides the necessary flexible support for motion in the slow speed scanning direction. Also, two-dimensional scanners conforming to the present invention use a gain-guided visible laser diode oriented in a particular manner so that the astigmatism of the laser beam extends the working range by compensating for decreasing fast direction scan line density at points farther away from the scanner.

摘要： An electronic stylus, for use with a computer having a digitizer, has a light emitter for emitting light to illuminate optically encoded information. A photodetector senses light reflected from the illuminated optically encoded information and produced an electrical signal representative of the optically encoded information. Stylus electronics provide positional input data by contacting a digitizer tablet with the stylus. The stylus housing contains the light emitter, photodetector and stylus electronics. A tip at a fore end of the housing is adapted for contact with the digitizer tablet and the light is emitted from other than the fore end of the housing.

摘要： A laser scanning head in which the range of the beam waist is varied independently of any measurement of the actual range of the symbol. The optical member is a condenser lens that is moved by energizing a magnetic coil; the lens is operated independently of the scanning movement of the laser beam, to produce a continuous, progressive variation (e.g., a continuous oscillation) in the range of the beam waist, so that at some point in the variation the spot size on the symbol will be of an appropriate size. The movement of the lens can be synchronized with the beam scan (e.g., so that the same spot size can be maintained for several scans). Spot size can be chosen adaptively, by varying the range of the beam waist until the contrast in the reflected light collected from the symbol exceeds a predetermined level.
