摘要
本文介绍了一种新型轻武器光电瞄具显示系统的结构和工作原理 ,利用数字信号处理器(DSP)的同步串行接口 ,以 10MHz速率产生视频字符的点阵信号 ,同时利用可编程逻辑器件 (PLD)产生大、小十字丝 ,最后将它们与视频信号叠加并在寻像器上显示出来。整个显示子系统具有结构简单、体积小、重量轻、资源占用少、瞄准直观等特点。目前该显示系统已经在某新型轻武器的光电瞄具中得到使用 ,达到了预期的效果。
The structure and theory of the display system for a new type of small arms optoelectronic sight is introduced. The system uses the synchronous serial port of a digital signal processor, which can produce dot matrix signal of video characters at a speed of 10MHz. At the same time, the programmable logic device generates the reticles. The reticle and the video characters are displayed on the monitor simultaneously. This system is characterized by its simple structure, small size and weight, needing fewer resources and simplicity in aiming. The display system has been applied in practice.
