The laser printer and illumination system includes laser diode arrays, array illumination optics and cross-array illumination optics. The cross-array illumination optics combine light beams from the laser diode arrays so as to illuminate a spatial light modulator and confine incident light within a cross-array width of the modulator.Field of SearchBy surface composed of lenticular elementsHaving particular chemical composition or structure Plural modulation cells Having particular composition Plural lenticular plates Particular focusing or defocusing characteristic Electro-optic With particular electrode structure or arrangement, or medium mounting structure or arrangement Identifying, composing, or selecting | |
