Zusammenfassung:A hand-supportable coplanar 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 a coplanar laser illumination and imaging based device having at least one visible laser diode (VLD) for producing a planar light illumination beam (PLIB). The code symbol reader further includes an 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 an image processing computer for processing the buffered digital linear images so as to read code symbols graphically represented in the digital linear images. During object illumination and imaging operations, a controller automatically controls the linear image formation and detection module, the PLIB producing device, the image frame grabber, and the image data buffer.
