Abstract
The present invention is an apparatus for digitally controlling the output of multiple laser diodes in a system that forms a plurality of scan lines in a Raster Output Scanning (ROS) system. Output of the laser diodes is digitally controlled by a multi-channel integrated circuit to eliminate propagation delay and linearity differences commonly found between single-channel modulation control devices.
