Abstract
A projection system for use with a polarized projection screen having a screen polarization direction. The projection system includes a projector operable to generate a polarized light output and project the polarized light output along a beam path towards the polarized projection screen. The polarized light output includes at least a first light component having a first polarization direction and a second light component having a second polarization direction orthogonal to the first polarization direction. The projection system also includes a waveplate received in the beam path. The waveplate is structured to rotate at least one of the first light component and the second light component such that the first light component and the second light component have a common polarization direction to be aligned with the screen polarization direction to minimize absorption loss of the polarized light output.
