Abstract
A laser printer (10) is comprised of a laser diode array (11), a cross array illumination optics (21), a laser lenslet array (24), a spatial light modulator (40), and a fly's eye integrator (23) which illuminates the spatial light modulator with flooded uniform light. In another embodiment the angular spectrum of the light incident to the spatial light modulator is tailored to enhance the quality of modulation. The spatial light modulator (40), is illuminated uniformly by laser diode emitters (12) comprising laser diode array (11), and the spatial light modulator (40) break up the light into image elements, which are subsequently imaged to a media plane (60), to form a desired pattern of spots.
