Patent abstract
A system to adjust light path length using a digital light path length modulator. The digital light path modulator includes an optical path length extender (OPLE) and a polarization modulator. The OPLE has two light paths having different path lengths, so light with a first polarization is directed through a first light path, and the light with a second polarization is directed through a second light path through the OPLE.
