    Abstract: A polarization conversion system separates light from an unpolarized image source into a first state of polarization (SOP) and an orthogonal second SOP, and directs the polarized light on first and second light paths. The SOP of light on only one of the light paths is transformed to an orthogonal state such that both light paths have the same SOP. A polarization modulator temporally modulates the light on the first and second light paths to first and second output states of polarization. First and second projection lenses direct light on the first and second light paths toward a projection screen to form substantially overlapping polarization encoded images. The polarization modulator may be located before or after the projection lenses. The polarization-encoded images may be viewed using eyewear with appropriate polarization filters.

    Abstract: The present application provides a single lens capture device having a single input port. The single lens capture device may include an objective lens, a fixed objective lens aperture, off-center apertures inside the objective lens, and a sensor. The sensor is operable to capture images at a rate of at least two times the rate of stereoscopic presentation.

    Abstract: Disclosed is a light guiding valve apparatus including a light valve, a two dimensional light emitting element array and an input side arranged to reduce light reflection for providing large area directional illumination from localized light emitting elements with low cross talk. A waveguide includes a stepped structure, in which the steps may include extraction features hidden to guided light propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. Stray light falling onto a light input side of the waveguide is at least partially absorbed.

    Abstract: A projection system includes first and second illumination sources and a homogenizer component. The first illumination source has a first numerical aperture value. The second illumination source has a second numerical aperture value lower than the first numerical aperture value. The homogenizer component on the illumination path is configured to receive light from both the first and second illumination sources. A projection lens in the imagining path is configured to receive an image data stream that includes a sequence of image frames having an image frame period. The first and second illumination sources are configured for modulation at a rate equivalent to the image frame period. One or more active irises may perform the modulation.

    Abstract: Disclosed embodiments relate to a stereoscopic projection system and methods. An exemplary disclosed projection system includes an optical component disposed between the lenses of a lens arrangement. An exemplary lens arrangement includes a first power group, a second power group, and an aperture stop. In an embodiment, the optical component is disposed between the first power group and the aperture stop. In an exemplary embodiment, the optical component is proximate to the aperture stop. By disposing the optical component closer to or proximate to the aperture stop in the lens arrangement, various benefits may be realized, including improved contrast uniformity.
