ABSTRACT:
An electronic trapping implementation in imager with laser driver is provided by comparing an output image from the imager to a reference image to obtain a difference image and calculating one or more frequency and amplitude modulations based on the difference image and applying the one or more frequency and amplitude modulations to the imager until the difference image is eliminated.
