作者提出了一种新型的FLOATS(Flesnel-Lens-Based光学仪器可触摸距离立体观察)系统。自动立体显示浮子结合了视差演示和镜头生成的真实图像，以显示观众可以接触到的逼真的3D图像。在传统的彩车中，使用偏振滤光片或液晶百叶窗来分离投射到眼睛上的图像，这造成了串扰噪声和亮度降低。本文提出用组合镜代替滤镜或快门来实现视差呈现。在该系统中，右眼和左眼的图像在屏幕上并排显示。然后组合的反射镜反射每个图像，将其移到中心，使得该系统的光学几何可能与传统的浮动显示器完全相同。这种新方法既避免了串扰噪声，又避免了亮度的降低，并能够呈现更逼真的3D图像，给观众带来的眼睛疲劳更少。此外，该系统还可以使用LCD面板作为屏幕部分，因为它只需要并排显示两个图像。结果，与传统系统相比，系统的尺寸减小。
The author presents a new version of FLOATS (Flesnel-Lens-based Optical Apparatus for Touchable-distance Stereoscopy) system. The autostereoscopic display FLOATS combines parallax presentation and real image generation by lenses to show realistic 3-D images within the reach of the viewer. In the conventional FLOATS, polarizing filters or liquid crystal shutters are used to separate images projected to the eyes, which has caused cross-talk noise and reduction of brightness. This paper proposes use of combined mirrors instead of filters or shutters to realize parallax presentation. In this system the images for the right eye and the left eye are displayed side by side on the screen. Then the combined mirrors reflect each image to shift it to the center so that the optical geometry of this system may be completely the same as the conventional FLOATS display. This new method avoids both cross-talk noise and reduction of brightness and enables presentation of more realistic 3-D image which gives less eyestrain to the viewer. In addition to it, a LCD panel can be used as the screen part of this system because it is only required to show two images side by side. As a result the size of the system is reduced compared with the conventional system.
