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: 7832643
Abstract: A hand-supportable planar laser illumination and imaging (PLIIM) based code symbol reader includes: a hand-supportable housing having light transmission aperture; a linear image formation and detection module having a linear image detection array; and a planar laser illumination beam (PLIB) producing device having at least one visible laser diode (VLD) for producing a planar light illumination beam (PLIB). The code symbol reader further includes image grabber for grabbing digital linear images formed and detected by the image formation and detection module, an image data buffer for buffering the digital linear images grabbed by the image grabber and constructing a two-dimensional image from a series of buffered linear digital images, and an image processing computer for processing the buffered two-dimensional digital image so as to read code symbols graphically represented in the two-dimensional digital linear image.

Patent number: 6978936
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.
