PROCESS AND DEVICE FOR CALIBRATING A LASER BEAM SCANNING CONTROL

摘要

A process is disclosed for calibrating a laser beam scanning control. A light-sensitive medium (5) is irradiated at predetermined positions by a laser beam (2) in order to generate a test image (20), then partial digital images of sections (21) of the test image (20) are generated and the digital partial images are assembled into a total digital image of the test image (20). The data for correcting the laser beam (2) scanning control (4) are calculated on the basis of a comparison between real positions of the laser beam (2) on the total digital image and predetermined set co-ordinates.
