Abstract: An infinity display device with autostereoscopic capability having one or more high lumen light sources 6, a transmissive spatial light modulator (SLM) 7, light collimating optics and a rectilinear light guide. Once the light has passed through the SLM 7 an objective 2 converges the image encoded rays toward a point 43 representing the entrance pupil 5 of said light guide. A second lens 1 then collimates the rays in one plane (Tangential) while a lenticular array 13 is used for collimating rays in the second plane (Sagittal). Next, a first surface mirror 9 reflects all said rays toward a triangular prism 10, where they undergo colour separation before entering the light guide. The light guide may itself consist of two, parallel, first surface mirrors 3 & 4 one of which is partially transmissive. Finally a Fresnel screen 11 tilts the light toward the observer.
