Paper Abstract

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.
