【摘要】 针对一般振镜式激光显示系统,介绍了该系统的组成、激光显示的原理以及计算机通过打印口对其进行控制的方法,改变了以往利用插卡的方式控制操作比较麻烦的情况;并且介绍了研制激光显示系统的理论基础,也就是振镜扫描原理。对图形的扫描也就是对该图形曲线上一系列坐标的扫描,即数字化的图形,因此用软件控制振镜是可行的;还阐述了该系统在软件上的实现,采用多线程技术编程,从根本上解决了程序独占的问题。更多还原

【Abstract】 The composition of the popular laser display system,the principle of laser display and the method by which it is controled by the computer via LPT are introduced.Theory of mirror scan is described forms the theoretic basis of laser display.In additon,a method by means of Multithread is described,which solves the problem of programme monopolize.更多还原
