描述了一种先进的自动立体显示器，其允许由几个人同时观察立体对，而不需要为观看者使用特殊的眼镜和任何种类的头部跟踪设备。该系统由右眼系统、左眼系统和复杂的头部跟踪系统组成。在每眼系统中，使用透明型彩色液晶成像板，并带有特殊的背光单元。背光单元由单色2D显示屏和大幅面凸透镜组成。该装置只分配观看者正确的每只眼睛的光。右眼透视系统通过半反射镜与左眼透视系统组合，以便用作时间平行立体系统。观众的红外图像通过大幅面凸透镜拍摄并聚焦，并作为调制的二进制半面图像反馈到背光。自由立体显示器采用TTL方法作为精确的头部跟踪。该系统作为立体电视电话在杜克大学远程医学系和名古屋大学医学院放射科之间使用GIBN的高速数字线路工作。本文还介绍了其应用。
An advanced auto-stereoscopic display is described that permits the observation of a stereo pair by several persons simultaneously without the use of special glasses and any kind of head tracking devices for the viewers. The system is composed of a right eye system, a left eye system and a sophisticated head tracking system. In the each eye system, a transparent type color liquid crystal imaging plate is used with a special back light unit. The back light unit consists of a monochrome 2D display and a large format convex lens. The unit distributes the light of the viewers' correct each eye only. The right eye perspective system is combined with a left eye perspective system is combined with a left eye perspective system by a half mirror in order to function as a time-parallel stereoscopic system. The viewer's IR image is taken through and focused by the large format convex lens and feed back to the back light as a modulated binary half face image. The auto-stereoscopic display employs the TTL method as the accurate head tracking. The system was worked as a stereoscopic TV phone between Duke University Department Tele-medicine and Nagoya University School of Medicine Department Radiology using a high-speed digital line of GIBN. The applications are also described in this paper.
