ABSTRACT:
A light engine for a single panel scrolling color projection display system employs a light guide to guide light from a source through unequal path lengths to an output lens. The light guide is characterized by little or no light loss or increase in etendue (angular extent) regardless of path length, resulting in a compact arrangement having high performance and low cost.
