Abstract
A projection system comprising a first imaging component, at least a second imaging component, and a color combiner. The first and second imaging components each comprise an imager and a reflective polarizer that is configured to at least partially separate a light beam from the imager into a first portion and second portion, where the first portion and the second portion have substantially orthogonal polarization states. The first portions of the light beams are directed in the same direction above or below a plane defined by the second portions of the light beams. The color combiner is configured to combine the second portions of the light beams, where the second portions of the light beams have substantially orthogonal polarization states prior to entering the color combiner.
