Integral Floating 3-D Display Using Two Retro-Reflector Arrays

We propose an integral floating display using two retro-reflector arrays. The proposed method is composed of an integral imaging display, a half mirror, and two retro-reflector arrays. In this paper, the depth-resolution limit and the small complete viewing range for real image in conventional integral imaging are theoretically analyzed, and can be improved much in the proposed method. The floating 3-D image looks of high-quality with smooth surface without the influence of the lens array structure. Experiments are performed to verify the method.
