Abstract

In the paper, the working principle of graphic output by wise laser large screen displayer is introduced. By study on the working principle of galvanometer scanning and the relations between with the deflection angle of galvanometer and the scanning point of laser in large screen, the methods of correcting the graphic distortion due to galvanometer scanning are investigated.
