The Cambridge autostereoscopic three-dimensional display is a time-multiplexed device that gives both stereo and movement parallax to the viewer without the need for any special glasses. This analysis derives the size and position of the fully illuminated, and hence useful, viewing zone for a Cambridge display. The viewing zone of such a display is shown to be completely determined by four parameters: the width of the screen, the optimal distance of the viewer from the screen, the width over which an image can be seen across the whole screen at this optimal distance, and the number of views. A display's viewing zone can thus be completely described without reference to the internal implementation of the device. An equation that describes what the eye sees from any position in front of the display is derived. The equations derived can be used in both the analysis and design of this type of time-multiplexed autostereoscopic display.
剑桥自动立体三维显示器是一种时分复用设备，无需任何特殊眼镜就能为观看者提供立体效果和运动视差。该分析得出了剑桥显示器全亮且因此有用的观看区域的大小和位置。这种显示器的观看区域被证明完全由四个参数决定：屏幕宽度、观看者与屏幕的最佳距离、在此最佳距离下能在整个屏幕上看到图像的宽度以及视图数量。因此，无需参考设备的内部实现方式就能完整描述显示器的观看区域。推导出了一个描述眼睛从显示器前方任何位置所看到内容的方程。所推导的方程可用于此类时分复用自动立体显示器的分析和设计。
