Abstract
An infinity display device with autostereoscopic capability having one or more high lumen light sources, a transmissive spatial light modulator (SLM), light collimating optics and a rectilinear light guide. Once the light has passed through the SLMan objectiveconverges the image encoded rays toward a pointrepresenting the entrance pupilof said light guide. A second lensthen collimates the rays in one plane (Tangential) while a lenticular arrayis used for collimating rays in the second plane (Sagittal). Next, a first surface mirrorreflects all said rays toward a triangular prism, where they undergo colour separation before entering the light guide. The light guide may itself consist of two, parallel, first surface mirrors&one of which is partially transmissive. Finally a Fresnel screentilts the light toward the observer.
