Zusammenfassung:A head-up display system and method are provided that suppress double images from a combiner by eliminating or reducing a reflection of a refracted image from the back surface of the combiner. The combiner contains a tilted axis polarizing structure that attenuates transmittance and subsequent reflection of a refracted polarized projector image but maintains high transmittance for the forward external scene imagery.
