Abstract
A system is provided for rendering an output image on an image transfer surface using multiple optical scan paths in an image rendering device. The system includes a plurality of lasers, a plurality of scan time detectors, and processing circuitry. Each of the lasers is configured to generate an optical scan path on the surface. Each scan time detector is associated with a corresponding laser and is operative to measure scan time of the laser along the respective optical scan path. The processing circuitry communicates with each scan time detector and is operative to generate a video signal having a video frequency associated with the scan time detected for the respective laser. A method is also provided.
