Abstract: Methods of and systems for illuminating objects using planar laser illumination beams (PLIBs) having substantially-planar spatial distribution characteristics that extend throughout the field of view (FOV) of image formation and detection modules employed in such systems. Each PLIB is produced from a planar laser illumination beam array (PLIA) comprising a plurality of planar laser illumination modules (PLIMs). Each PLIM comprises a visible laser diode (VLD), a focusing lens, and a cylindrical optical element arranged with each PLIM, which is adjustable relative to other PLIMs so as to permit precise positioning of each PLIM relative to the optical axis of the imaging optics of the image formation and detection module. The individual PLIB 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.

Abstract: A device including at least one image detection array and image formation optics that provide a field of view corresponding to the image detection 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 image detection 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 image detection array to thereby reduce speckle noise in images captured by the image detection 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 image detection array.

Abstract: A fully automated package identification and measuring system (300), in which an onmidirectional holographic scanning tunnel (100) is used to read bar codes on packages entering the tunnel, while a package dimensioning subsystem (500, 600) is used to capture information about the package prior to entry into the tunnel. Mathematical models are created on a real-time basis for the geometry of the package and the position of the laser scanning beam used to read the bar code symbol thereon. The mathematical models are analyzed to determine if collected and queued package identificaton data is spatially and/or temporally correlated with package measurement data using vector-based ray-tracing methods, homogeneous transformations, and object-oriented decision logic so as to enable simultaneous tracking of multiple packages being transported through the scanning tunnel.
