<title>Multiperspective autostereoscopic display</title>

Abstract

We present a design for a 3D display system that is simultaneously autostereoscopic (no viewer eyewear is required), multiperspective or look-around (horizontal parallax is achieved without head tracking), raster-filled (all pixels have gray scale), and dynamic (live or real-time scenes may be displayed). This system will enable the demonstration of improved pilot performance and situation awareness due to multiperspective (i.e., look-around) viewing capability. The system uses twenty separate small liquid crystal televisions (LCTVs) with corresponding perspective views projected onto a pupil-forming screen consisting of a Fresnel lens and a pair of crossed lenticular arrays. The system will provide design data necessary for the development of a more compact and optically efficient system that uses digital micromirror devices instead of LCTVs.
