Abstract

An image projection system has two illumination beams of different colors. A first polarizing beamsplitter (PBS) has first and second input faces. Light of the first color is incident on the first input face and the light of the second color is incident on second input face. At least some of the light of the first color propagates from the first PBS to a first imager unit via a second PBS. The light of the second color propagates from the first PBS to a second imager unit via, in some embodiments, the second PBS and, in other embodiments, via a third PBS. One type of PBS includes a polarizing layer and a dichroic optical layer that is substantially transparent for light of the first color in a first polarization state and is substantially reflective for light of the second color in a polarization state orthogonal to the first polarization state.
