Title: Laser printer utilizing a spatial light modulator

Abstract: A laser printer utilizes a total internal reflection spatial light modulator that is optimized to work with a partially coherent laser source. The laser source is a laser diode array having a plurality of multi-mode emitters. The spatial light modulator diffracts light from said laser source according to an applied electric field. A spatial filter having a slit passes designated diffracted light which corresponds to an applied electric field and the light is ultimately imaged onto an image plane by way of an imaging lens.
