    摘要: The method and apparatus of this invention facilitate operation of a bar code reader over a wider range of working angle and for a wider range of bar code densities. The invention includes improved optics and sensing elements. The optics and sensing elements and/or the associated circuitry are arranged to provide two channels of data derived form the scanned bar code. The two channels have differing resolutions. Analysis of the data from the two channels provides a single decoded result. As the working angle and density vary at least one of the resolutions will be appropriate for sensing all or most of the bar coded data. The data from the channel producing a valid result can be used, or if neither channel produces a valid result by itself, data from each channel can be analyzed and valid portions of the data from both channels combined to produce the single decoded result.

    摘要: A scan module in a reader for, and a method of, electro-optically reading symbols, include a light source for directing light at a symbol during reading, a light detector for detecting return light from the symbol during reading and for generating an electrical signal indicative of the detected return light, and an object sensor for sensing an object bearing the symbol and for generating a trigger signal for initiating the reading. The light source, the light detector and the object sensor are all supported by a common chassis.

    摘要: A target is illuminated with illumination light for image capture by a solid-state imager of an imaging reader. Internal reflections of the illumination light at a window are minimized, if not eliminated, by configuring the window as a non-planar optical element operative for redirecting the internal reflections away from the imager to enhance reader performance.

    摘要: A plurality of solid-state imagers is mounted in a reader, such as a bi-optical, dual window, point-of-transaction workstation, for capturing images along different fields of view of diverse targets useful for customer identification, customer payment validation, operator surveillance, and coded indicia. The imagers are commonly mounted on a circuit board for joint installation at, and joint removal from, the reader for ease of serviceability.

    摘要: A substantially uniform distributed illumination pattern of light is generated on and along a symbol to be read by image capture. A solid-state imager is mounted on a tilted printed circuit board in a tilted handle of an ergonomic reader. An imaging lens assembly captures return light over a field of view from the symbol along an imaging axis, and projects the captured return light onto the imager. An illumination light source is mounted on the board for emitting illumination light at an acute angle of inclination relative to the imaging axis. An optical component includes a first lens portion with a polynomial incident surface for intercepting, bending and aligning the emitted illumination light to generate the pattern in a scan direction along the symbol, and a second lens portion with a toroidal or cylindrical aspherical surface for collimating the aligned illumination light to generate the pattern in a transverse direction.

    摘要: A bioptical workstation includes plural image capture modules for capturing images of indicia along different fields of view. Each module includes an illuminator for illuminating the indicia with illumination light, a megapixel imager with a rolling shutter for sequentially capturing the return light, and a shutter element for passing the return light to its imager in an open state, and for blocking the return light from other modules from reaching its imager in an closed state. A controller prevents interference among the modules by controlling the shutter element to assume the open state only during a respective exposure time period during which its imager produces an electrical signal indicative of the indicia, and by controlling the shutter element to assume the closed state at all times other than the respective exposure time period to prevent capture of the return light from the other modules.
