摘　　要：本文概述了一种用于图文信息输入计算机的高分辨率光电扫描系统。一张幅面为A_3的图纸可以在90s之内被扫描完毕,且扫描分辨率为250dots/2.54cm。文章讨论了该系统的机、光、电、计算机及软件等各方面的基本原理及系统机电一体化的关键技术。This paper presents a high resolution photoelectric scanner system which has been developed in order to input image information into the computer. A paper with format of 297mm×420mm can be scanned in 90 seconds, and the scanning resolu tion is 300 dots/inch. A pattern recognizing software system has also been developed to transform the scanned matrix patterns to the vector patterns so that the image signals may be edited, modified and plotted.
