ABSTRACT:
The present invention is a novel raster output scanner (ROS) configuration that employs modulated laser diodes as the light source. Each laser diode is coupled to a dedicated driver that modulates the light beam according to digital video signal data. The present invention employs a single-channel acoustic-optic cell that deflects the multiple beams to maintain proper facet tracking. A single transducer is coupled to the single-channel acoustic-optic cell that generates the necessary acoustic wave to maintain proper tracking.
