Abstract
Retro-reflection based projection 3D display with low crosstalk is proposed. The 3D display consists of a retro-reflective sheet, an image projector array, a vertical scattering layer, and two optical noise sources projectors. The image projector array is used to provide parallax images. The retro-reflective sheet is used to reflect parallax images to different horizontal viewpoints to form 3D images. The vertical scattering layer is used to scatter the reflected light in the vertical directions, and form viewing areas in the vertical projection area of each corresponding projector. The optical noise source projector provides salt and pepper noise to reduce crosstalk. A prototype of the proposed 3D display is developed, and the experiment results agree well with the theory.
