Abstract

Laser imaging system for imaging printed circuit artwork on an output medium such as a photosensitive film, a glass plate or a printed circuit board. The laser beam scans the output medium and is modulated in accordance with the image to be formed. A correction signal is applied to the modulator to maintain substantially uniform exposure across the output medium notwithstanding variations in the velocity of the beam.
