Abstract: An apparatus (110), system (100), and method (900) for displaying an image (880). Instead of using an expensive configuration of prisms (310) such as TIR prisms (311) or RTIR prisms (312) to direct light (800) to and from a DMD (324), a plate (340) with transmissive (374), reflective (372), and/or polarization (373) characteristics is used. The plate (340) can be implemented in a wide variety of different embodiments using a wide variety of different components and configurations.

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.

Abstract: A system to adjust light path length comprising a digital light path length modulator, the digital light path length modulator comprising a polarization modulator to receive polarized light and to modulate a polarization of some or all of the polarized light. The system further comprising an optical path length extender (OPLE) having an entry surface and an exit surface, to direct the light entering the OPLE with a first polarization through the entry surface and along a first light path through the OPLE to exit through the exit surface, and to direct the light entering the OPLE with a second polarization through the entry surface and along a second light path through the OPLE to exit through the exit surface, the second light path through the OPLE having a light path length two or more times longer than the first light path length through the OPLE.

Abstract: A media chair apparatus (200), system (100), and method (900). The media chair apparatus (200) includes a support assembly (400) that can be at least temporarily substantially fixed in an at least substantially fixed position while a seat assembly (300) rotates relative to the support assembly (400). A port (500) in the support assembly (400) can be used to interface with the operating environment (80) while a port (500) in the rotatable seat assembly (300) can be used to interface with a portable access device (150) used by the user (90) to access or otherwise enhance a media experience (800).

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

Abstract: A system to adjust light path length comprising a digital light path length modulator is described. The digital light path length modulator comprises 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.

Abstract: An image capture system comprising an optical path length extender (OPLE) to direct the light having a first polarization through a first light path through the OPLE, and to direct the light having a second polarization through a second light path through the OPLE, the first and second light paths having different light path lengths. The image capture system further comprising an image sensor to capture a plurality of image portions at a plurality of focal distances.

Abstract: A system (100), apparatus (110), and method (900) for displaying an image (880). The light (800) in the image (880) is modified by a tuning assembly (700) to possess more than one focal point (870). Thus a single image (880) can include multiple depth regions (860). Each depth region (860) can be comprised of light (800) possessing a distinct focal point (870). The tuning assembly (700) can be implemented in the form a tunable lens (710), a tunable lens array (720), a movable lens (730), or a deformable mirror (740).

Abstract: A system (100), apparatus (110), and method (900) for displaying an image (880). The system (100) can use an aspherical lens (450) to direct light (800) in the interim image (850) towards the viewer (96) of the final image (880) displayed by the system (100). Use of the aspherical lens (450) expands the FOV (860) accessible to the viewer (96) and reduces exit pupil drift (480).
