Research on a Laser On-Line Marking System Using Galvanometer;

This paper give the principle of the semiconductor Laser TV, expatiated the method of using Polygon prism rotating mirror which driven by the per-magnetism brushless motor to do the horizontal scanning and using Galvanometer which driven by the stepping motor to do the vertical scanning, and give the analysis of the running result.

As a response to the speed, high marking quality, enclosed beam and environment adaptable advantage, galvanometer-based optical scanners laser marking machines is becoming the mainstream and the develop direction of laser marking machines.

This paper direct three primary colors solid state lasers which are as the light source,spectroscopes which are used to produce color beams of light,two galvanometers systems which are used to scan.

The construction and the principle of the two-dimensional galvanometric scanner laser scanning system are theoretically described.

Theory of mirror scan is described forms the theoretic basis of laser display.

Study on Galvanometer Scanning Fiber Laser Welding Plexiglass Technology

Based on marking status, the structure , theory and problems of the galvanometer scanning laser mark system are elaborated with emphasis on hardware and software.

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.
