ABSTRACT:
Apparatus for illuminating a spatial light modulator combines radiation from two or more multiple-emitter laser diode arrays. Brightness is conserved. The apparatus includes collecting optics which includes an array of microlenses. The microlenses steer beams of radiation which issue from individual emitters so that the beams overlap at a target plane to produce a desired beam profile.
