Abstract
An autostereoscopic 3-D image is provided in a viewing zone without the need for 3-D glasses by use of one or more projectors that project two or more images having projected exit pupils separated horizontally by no more than an average human interocular spacing onto a 3-D forming screen (which is a lenticular or a raster barrier screen) with a substantially smooth and nominally white back projection surface and a front side with multiple individual vertical elements that project left and right images so that the 3-D forming screen retro-reflects projected light on the screen received from a light source back to the light source.
