Abstract
A light source includes a first set of first beam sources having parallel output beams lying in a first-beam-source plane and a second set of second beam sources having parallel output beams lying in a second-beam-source plane. The first-beam-source output beams are parallel to the second-beam-source output beams, but are spatially offset in a direction perpendicular to the first-beam-source output beams. A spatial optical interleaver disposed receives the first-beam-source output beams and the second-beam-source output beams. The first-beam-source output beams pass unimpeded through a set of first-beam openings in the spatial optical interleaver, and the second-beam-source output beams are reflected parallel to the first-beam-source output beams and in the first-beam-source plane.
