摘　　要：本文报道以RDS立体图作为检测图形，用液晶开关实现其三维立体显示的一些探索性研究。用液晶开关眼镜作为立体困的同步分离部件，使得本系统建立于继时法成像的基础上，因而消除了“红绿竞争”等影响检出精度的因素；系统采用帧须作为同步切换的总投信号，使CRT的视页切换与液晶眼镜开关同步，为此而开发出的显示寄存器编程技术解决了CRT视页切换的超高速要求．Some rearches are reported in the paper,such as showing stereogram with liquid-crystal switchesand RDS(Random Dot Stereogram). The stereogram showing system is a time-unchained system because of use-ng liquid-crystal switches,so it can solve some factors that redued th system precision,example for red-greencompeting pHenomena,Vedio frenquency signs can control the switching actions of CRT and liquid-crystal glass-es,so their actions become symchronizition. Through programming the vedio registers,we can fit the velocity thathas been requested in vedio page switching process.
