Abstract
A digital illumination and imaging system employing one or more planar laser illumination modules (PLIMs) each including: (i) a laser illumination source driven preferably by high frequency modulated (HFM) diode current drive circuitry; (ii) a beam collimating optics disposed beyond the laser source; (ii) an optical beam multiplexer (OMUX) device disposed beyond the collimating optics; and (iv) a planarizing-type illumination lens array disposed beyond the OMUX device, and arranged for generating a plurality of substantially planar coherence-reduced laser illumination beams (PLIBs) that form a composite substantially planar laser illumination beam (PLIB) having substantially reduced spatial/temporal coherence. A digital image detection array for detecting digital images of an object illuminated by the composite substantially planar laser illumination beam. By virtue of the present invention, the power of speckle pattern noise, observed in a digital image of an object detected at the digital image detection array, is substantially reduced when the digital image is formed using the substantially planar laser illumination beam.
