    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 solid-state imager is mounted in a reader, such as a bi-optical, dual window, point-of-transaction workstation, for capturing light along an optical axis over a field of view from diverse targets useful for customer identification, customer payment validation, operator surveillance, and coded indicia. An optical converter is located within the housing, for optically modifying and asymmetrically magnifying the field of view along mutually orthogonal directions generally perpendicular to the optical axis, and for increasing resolution of the imager along one of these directions.

    摘要: An imaging based bar code reader for imaging and decoding a target bar code. The reader features a housing including a scanning head defining a horizontal axis and an imaging system supported by the housing for imaging the target bar code. The imaging system including a 2D sensor array and focusing optics receiving reflected illumination from the target bar code through the window and focusing the reflected illumination onto the sensor array. The sensor array includes an orthogonal array of pixels and defines a horizontal axis. The reader further features a decoding system for decoding an image of the target bar code. The sensor array is oriented such that the horizontal axis of the sensor array is at an acute angle with respect to the horizontal axis of the target bar code when the target bar code is being presented to the scanning head such that the horizontal axis of the target bar code is substantially parallel to the horizontal axis of the scanning head.

    摘要: A bar code reader capable of working over a wider range of working angle and for a wider range of bar code densities, using improved optics and sensing elements. The optics and sensing elements and/or the associated circuitry are arranged to provide two channels of data derived from 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. The different resolution of the two channels can be provided using different size photodetection areas, e.g., small and large groups of active areas on a sensor array.
