Polarized heads up display

摘要: A head-up display for vehicle including a windshield having first and second opposing air interfaces partially reflecting imaging illumination at predetermined interface to produce primary virtual image viewable by the operator of vehicle, half-wave retarder interposed between rotating linear polarization transmitted therethrough. An source provides linearly polarized an angle which is selected enhance reflection S-polarized light transmission P-polarized light, with being so as provide beam splitting interface.
