  • Patent number: 7600689
    Abstract: Methods of and systems for illuminating objects using planar laser illumination beams having substantially-planar spatial distribution characteristics that extend through the field of view (FOV) of image formation and detection modules employed in such systems. Each planar laser illumination beam is produced from a planar laser illumination beam array (PLIA) comprising an plurality of planar laser illumination modules (PLIMs). Each PLIM comprises a visible laser diode (VLD, a focusing lens, and a cylindrical optical element arranged therewith. The individual planar laser illumination beam components produced from each PLIM are optically combined to produce a composite substantially planar laser illumination beam having substantially uniform power density characteristics over the entire spatial extend thereof and thus the working range of the system.

  • Patent number: 7584893
    Abstract: A tunnel-type digital imaging system for use within retail shopping environments such as supermarkets. The system includes a tunnel configuration arranged about a conveyor structure for transporting objects therethrough, and an image capturing and processing subsystem embodied within the tunnel configuration, for generating a 3D digital imaging volume above the conveyor structure and within the tunnel configuration, for capturing digital 1D images of objects transported through the 3D digital imaging volume. The image capturing and processing subsystem includes a plurality of illumination and imaging stations. Each station includes a 2D imaging array having optics providing a 3D field of view (FOV) on the 2D imaging array that is projected and extends into the 3D digital imaging volume, and one or more light emitting devices configured together to produce an illumination beam that extends into the 3D FOV of the 2D imaging array.

  • Patent number: 7527200
    Abstract: A hand-supportable planar laser illumination and imaging (PLIIM) based device having hand-supportable housing with a light transmission aperture. A linear image formation and detection (IFD) module is mounted within the housing, and has a linear array of image detection elements and also image formation optics with a field of view (FOV). When an object is presented within the FOV, the FOV focuses a linear image of the object onto the linear array. At least one planar laser illumination module (PLIM) is mounted on the support platform, with the linear IFD module, and produces a planar laser illumination beam (PLIB) spatially aligned with respect to the FOV and arranged in a coplanar relationship with at least a portion of the FOV. A laser beam despeckling mechanism is integrated in the device, for reducing speckle-pattern noise observed the linear digital images formed and detected at the linear array of image detection elements.

  • Patent number: 7513428
    Abstract: An imaging device including at least one imaging array and image formation optics that provide a field of view corresponding to the imaging array. At least one illumination module (which includes at least one source of coherent illumination) produces planar light illumination that substantially overlaps the field of view corresponding to the imaging array. Illumination control circuitry modulates the power level of illumination produced by the source of coherent illumination during each photo-integration time period of the imaging array to thereby reduce speckle noise in images captured by the imaging array. The illumination control circuitry preferably modulates the power level of illumination by controlling the number and/or duration of time periods corresponding to different power levels of illumination produced by the source of coherent illumination during each photo-integration time period of the imaging array.
