采用64块彩色液晶面板来实现自然的3D显示。采用改进的二维对准远心光学系统，将显示在液晶面板上的64幅图像投影在不同的水平方向上。由于在水平方向上的投影角度俯仰小至0.33度，观察者的眼睛可以聚焦在三维图像上。由于投影系统是远心的，图像离焦很小，因此在3D空间中生成清晰的3D图像。水平视角21.2度，3D屏幕尺寸为192mm X 151mm（9.6英寸）。3D物体可显示在3D屏幕前后~ 400mm范围内。原型3D显示器具有以下特点：a)不需要佩戴3D眼镜，b)多人同时观察，c)不受观察位置的限制，d)兼容人类3D感知，e)提供高存在感，f)提供逼真和移动的3D图像。人体对原型三维显示器的适应反应与真实三维物体的适应反应非常相似。
Sixty-four color LCD panels were employed to implement a natural 3D display. Sixty-four images displayed on the LCD panels are projected in the different horizontal directions by using modified 2D aligned telecentric optical systems. Because the projection angle pitch in the horizontal direction is as small as 0.33 degree, observers’ eyes can focus on the 3D images. Because the projection systems are telecentric, images are defocused little so that clear 3D images are generated in the 3D space. The horizontal viewing angle is 21.2 degrees, and the 3D screen size is 192 mm X 151 mm (9.6 inch.) The 3D objects can be displayed in the range of ~ 400 mm both in front of and behind the 3D screen. The prototype 3D display has following features: a) no need of wearing 3D glasses, b) simultaneous observation by multiple persons, c) no restriction on observing position, d) compatible with human 3D perception, e) providing high presence, and f) offering photorealistic and moving 3D images. The human accommodation responses to the prototype 3D display are very similar to those obtained for real 3D objects.
