Title:


    Slit-based Light Field 3D Display

Presenter(s):


Entry Number: 22


Description:


    The principle of glasses-free 3D displays (each eye sees a different image without wearing glasses) can create a fully natural sensation of depth. In conventional principles, lenticular lenses or parallax barriers are placed in front of an image source, such as a liquid crystal display, to allow it to show a stereoscopic image. A disadvantage of the technology is that the resolution of perceived images is limited by the diffraction at the lenticular lenses or parallax barrier. To overcome this limit, we improved the technique by using the human perceptual feature known as slit viewing. When a figure moves behind stationary narrow slits, observers can see the moving figure as an integrated whole, a phenomenon known as slit viewing.
