Abstract

Based on the mathematical analysis for optics of the laser scanning system, the mechanisms of the graphic distortion in the laser display has been studied. After considering the beam trace from image plan to galvanometer, a relation between the image points on the screen and the scan angles was built. Thus, it has been able to rectify the scanning linear distortion and pincushion error by computer software effectively.
