    摘要： 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.

    摘要： 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. Preferably, each planar laser illumination beam component is focused so that the minimum beam width thereof occurs at a point or plane which is the farthest or maximum object distance at which the system is designed to acquire images, thereby compensating for decreases in the power density of the incident planar laser illumination beam due to the fact that the width of the planar laser illumination beam increases in length for increasing object distances away from the imaging optics. By virtue of the present invention, it is now possible to use both VLDs and high-speed CCD-type image detectors in conveyor, hand-held and hold-under type scanning applications alike, enjoying the advantages and benefits that each such technology has to offer, while avoiding the shortcomings and drawbacks hitherto associated therewith.

    摘要： In a planar light illumination and imaging (PLIIM) system, a planar light illumination module (PLIM) of compact construction produces a planar laser illumination beam (PLIB) which emanates substantially within a single plane along the direction of beam propagation towards an object to be optically illuminated and imaged. The PLIM comprises a module housing which has an axial extent, first and second end portions, a central bore formed along the axial extent, and a recess integrally formed in the second end portion. A visible laser diode (VLD) is mounted along the bore at the first end portion of the module housing, for producing a laser beam generally along the axial extent. A focusing lens is mounted along the bore between the first and second end portions, for focusing the laser beam to a predetermined focal point. A laser beam expansion element is mounted within the recess at the second end portion of the module housing, and expanding the laser beam along a predetermined direction and producing a substantially planar laser illumination beam from the beam expansion component.
