Abstract
DTI has demonstrated new optical configurations designed to project autostereoscopic images to very large sizes using only one display and projector. They will allow the creation of large (50 cm and greater) immersive high resolution autostereoscopic displays with advanced features like head tracking and/or look around imaging. Previous autostereoscopic projection devices have used multiple displays in combination with multiple projectors, with attendant complexity and expense. The basic technique uses a small LCD to create viewing zones within a single large projection lens, of the type normally used for projection television applications. The lens images the LCD onto a large Fresnel lens. The Fresnel lens in turn re-images the viewing zones into the space in front of it. In this arrangement, the viewing area is limited to roughly twice the size of the lens that is used for projection. Methods used to expand the viewing area will be described.
