ABSTRACT:
In an image projection system, there are at least two light illumination units producing illumination light beams of respective first and second primary colors. A first beamsplitter is disposed to split at least a portion of the first illumination light beam into sub-beams, one of which is directed to a first image-forming panel. The other sub-beam is combined with at least some of the second illumination light beam to form a light beam of mixed light that illuminates the image-forming panel. In some embodiments, the first beamsplitter is a polarizing beamsplitter.
