摘　　要：基于双目视差原理,提出了一种新型的周视悬浮裸眼立体显示系统。采用菲涅尔透镜和单向散射屏实现了观察范围的纵向拓展,形成的三维图像可周视观看,有悬浮感且可触摸。对系统中采用的定向屏、旋转光阑、条状出瞳,以及投影机的投影距离进行了分析和设计。经过实验验证,立体图像合像舒适,显示效果明显。A new type of panoramic and suspending stereoscopic display system based on parallax principle is pro posed. Fresnel lens and a one-dimensional scattering screen are used to expand the longitudinal range of view. The three dimensional pictures displayed are panoramic, suspending, as well as tangible. The parameters of directional screen, ro tating stop, stripe exit pupil and the proiection distance of proiector are analyzed. A panoramic and suspending stereo- scopic display system is built to verify the validity of the system. The visual comfort of combined stereoscopic pictures and the display effect are both desirable.
