Computer Controlling Laser Two-Dimension Scanning Complex Figure Progressing

Today is the day of the development of science and technology ?people may have so many requirements that accelerate the refreshment of products .In many fields of manufacture and machining ,and as a special power , laser can produce the products that people could not dreamed .In the application of laser .scanning is widely applied just like lettering .measure , military and so on .Because of the special characters 梕xcellent direction .exclusive color and intense correlation .laser is applied more and more.This article begins from the introduction of scanning-laser and it's characters .then expounds gradually and in-depth the stepping-motor and Ipt of computer .And the next is the realization of all above.In the fourth chapter ,it is emphasized that the realization of two dimensions laser-scanning system .First, program is programming .then the signal of relevant control is export from computer to the stepping-motor .And the stepping-motor can running according to these control signals .so the system is completed successfully .This laser-scanning system can be applied in lettering .measure .military .manufacture and machining .earth-reconnoitering and so on .It may be used widely.
