由电子线路控制的大屏幕广告机、电子乐器的出现,以及舞台灯光的自动控制,已经使舞台产生了极好的效果。如果利用高亮度的激光束,通过计算机程序的变化控制图形和文字的变化,配合舞台背景、人物动作及舞台气氛,在大视野范围显示效果更好。高亮度的激光光斑能在通常照度环境、甚至在日光灯的照射下,仍可获得较理想的对比度。本文着重介绍 CMC-80双板机控制的激光大屏幕显示系统的构成及显示方法。
The advent of large-screen advertising machines, electronic musical instruments, and automatic control of stage lighting, controlled by electronic circuitry, has given the stage a tremendous effect. If the use of high-brightness laser beam, through the computer program changes control graphics and text changes, with the stage background, character movements and the stage atmosphere, in the larger field of view display better. High-brightness laser spot in the usual illumination environment, even in the fluorescent light irradiation, still can get a more ideal contrast. This article focuses on the CMC-80 double-board machine control of laser large screen display system and display method.
