Abstract
A light engine including polarization splitting lens unit comprises an illumination subsystem to create an entrance pupil and a polarization splitting lens unit including an angled polarized beam splitter (PBS) and including an entry face, a double pass face, and an exit face, the polarization splitting lens unit positioned in proximity to the illumination subsystem. The light engine further comprising imaging and illumination optics receiving the light from the polarization splitting lens unit, and a display element modulating the light received from the imaging and illumination optics, and reflecting the light back through the imaging and illumination optics. Wherein the polarization splitting lens unit receives the modulated light from the imaging and illumination optics, and outputs the modulated light through the exit face forming an exit pupil.
