Various kinds of optical image splitters find application in flat autostereoscopic display devices for image content separation. All type of parallax barriers have to deal with lack of transmittable intensity. In this paper we determine and modify geometrical and optical properties of cylindrical lens raster for two prototype 3D-displays with 5K resolution. Optical simulation analysis is used for the parameter studies and is compared with experimental measurements. To obtain thin adaptive lenses the alternative GRIN technology using liquid crystal lenses is investigated too. We determine the imaging performance in terms of luminance profiles in the nominal distance.
