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.
