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.

Polarized light direction system

A near-eye display system comprising an image source, a modulation stack, and an imaging assembly. The modulation stack, in one embodiment, comprises one or more digital light path length modulators.

Image capture with digital light path length modulation

A system to adjust light path length utilizing a digital light path length modulator is described. The digital light path length modulator includes a polarization modulator to receive polarized light and to modulate a polarization of some or all of the polarized light, and an optical path length extender (OPLE) to direct the light entering the OPLE with a first polarization along a first light path through the OPLE, and to direct the light entering the OPLE with a second polarization along a second light path through the OPLE, the second light path through the OPLE having a light path length longer than the first light path length through the OPLE.

Orthogonal optical path length extender

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

Digital light path length modulation

An apparatus (), system (), and method () for displaying an image (). Instead of using an expensive configuration of prisms () such as TIR prisms () or RTIR prisms () to direct light () to and from a DMD (), a plate () with transmissive (), reflective (), and/or polarization () characteristics is used. The plate () can be implemented in a wide variety of different embodiments using a wide variety of different components and configurations.

Apparatus, system, and method for displaying an image using a plate

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.
