Claim 13:
14. An illumination system, comprising:
a first angular-spatial light modulator (ASLM) subsystem having a first angular light modulator (ALM) comprising a first plurality of actuatable elements, wherein each of the first plurality of actuatable element configured to transition between an ON state having an ON angle and an OFF state having an OFF angle and further configured to project light into a first of at least three diffraction orders each corresponding to a first unique angle;
a second ASLM system having a second angular light modulator (ALM) comprising a second plurality of actuatable elements, wherein each of the second plurality of actuatable element configured to transition between an ON state having an ON angle and an OFF state having an OFF angle and further configured to project light into a second one of at least three diffraction orders each corresponding to a second unique angle,
wherein the first ASLM subsystem and second ASLM subsystem are positioned such that a first beam of light projected from the first subsystem at a first unique angle according to the first one of the at least three diffraction orders and a second beam of light projected from the second subsystem at a second unique angle according to the second one of the at least three diffraction orders will intersect.
