Abstract
A novel technique for homogenizing the multitude of beams emanating from a laser diode array is described, as it related to use as an illumination system in a laser printer. This illumination system was required to efficiently transform the multiple beams from a laser array into a single line of uniform light, incident upon a spatial light modulator array, without a loss of brightness. The importance of the laser diode source properties, including both spatial coherence and source Lagrange, will be considered relative to their impact on the system design. The design of the beam shaping optics, including the beam combiner optics and the fly's eye integrator assembly, will also be discussed. The implementation of this illumination system in a laser printer employing a modulator array will be discussed, including issues of alignment, component properties, and the results obtained during system integration.
