Abstract:
1. A system, comprising: a polarizing beamsplitter to combine a first polarized ray received from a first illumination system with a second polarized ray received from a second illumination system to form a combined polarized ray; a second polarizing beamsplitter to split the combined polarized ray into a first polarized component and a second polarized component, the first polarized component and the second polarized component having orthogonal polarizations to each other; a half-wave plate to rotate the second polarized component to the same polarization as the first polarized component; and a lens group to pass the first polarized component to a single image generator as a first polarized ray, and further to separately pass the second polarized component to the single image generator as a second polarized ray; wherein both the first and second illumination systems comprise:
