Abstract
A display system in which images from two displays that have the same optical polarization that is not affected by reflection by a beam splitter which combines images from the displays, and a half wave plate optical retarder to rotate plane of polarization of light from one display prior to impingement on the beam splitter, and a polarizer filter to block transmission to the beam splitter of leakage light caused by optical dispersion by the half wave plate. A display system in which images represented by polarized light from two displays are incident on a DBEF beam splitter, the direction of plane of polarization of one of the images relative to the DBEF is such that the DBEF preferentially transmits that direction and the direction of plane of polarization of the other of the images, which is directed to the other surface of the beam splitter, is such that the DBEF preferentially reflects that light.
