ABSTRACT:
An image projection device having a spatial light modulator and a polarized source system for illuminating the spatial light modulator such that light of a first polarization state illuminates one region of the spatial light modulator and light of a second polarization state illuminates another region of the spatial light modulator. Preferably, the image projection device includes a first set of polarization selective light processing elements, including a first conicoid element which passes light of the first polarization state and reflects light of the second polarization state and a second set of polarization selective light processing elements including a second conicoid element which passes light of the second polarization state and reflects light of the first polarization state.
