Planar laser illumination module (PLIM) employing high-frequency modulation (HFM) of the laser drive currents and optical multplexing of the output laser beams
A planar laser illumination module (PLIM) 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 illumination 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.
