Abstract:
A system including an optical path length extender (OPLE) having two light paths having different path lengths, such that light entering the OPLE with a first polarization is directed through a first light path, and light entering the OPLE with a second polarization is directed through a second light path through the OPLE. The OPLE includes a first polarization sensitive reflective element at a first angle to the light entering the OPLE and a second angled polarization sensitive reflective element at a second angle to the light entering the OPLE, the second angled polarization sensitive reflective element intersecting the first polarization sensitive reflective element.
