Abstract
Embodiments of a laser imaging system with uniform line illumination and method for generating images are generally described herein. In some embodiments, the laser imaging system includes a polarizer beam splitter to angularly separate an input laser beam into a pair of overlapping cross-polarized beams having a first angular separation therebetween, and a diffraction optic beamlet generator to generate a plurality of beamlets of alternating polarization states with a second angular separation therebetween. The laser imaging system may also include a focal-plane array (FPA) having a field-of-view (FOV) to be illuminated by the plurality of beamlets.
