    摘要: The invention provides an illumination system for a head-mounted display. The illumination system includes a plurality of illuminators which irradiate light over an area. The area has a central region where the light has a selective intensity, and outer regions on opposing sides of the central regions where the light has higher intensities than the selective intensity.

    摘要: Disclosed herein are apparatuses and methods for reclaiming the full field of view (FOV) of the original camera lens in a stereoscopic image capture system using an anamorphic attachment. Also disclosed are apparatuses and methods of projecting stereoscopic images on a fixed size screen from a single projector that was initially designed primarily for 2D operation. An exemplary apparatus may comprise an anamorphic afocal converter configured to halve a FOV of a camera or projector into two optical paths, and convert the halved FOVs into two full FOVs of the camera or projector. Such an apparatus may further comprise reflecting elements cooperatively arranged to direct two rectified images at a camera sensor or projection screen, where one or more reflecting elements receive the first of the two full FOVs and one or more reflecting elements receive the second of the two full FOVs.

    摘要: 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.

    摘要: Disclosed herein are light collectors for use in projection applications. The light collectors gather light from surface emitting sources (e.g., LEDs) of differing color (or same color in some embodiments) using input lightpipes. A light collection system splits the light into orthogonal linear polarization states and efficiently propagates the light by use of a polarizing beamsplitter (PBS) and a reflecting element to recycle light at a port of the PBS. Further, the light collection system may efficiently homogenize the light using an output lightpipe in a lightpath from the output of the PBS. In addition, the light collection system may present a single, linear polarization at the output through the use of a half-wave switch (LC cell) in some embodiments or ColorSelect filter in other embodiments. The light collection system may be integrated into a single, monolithic glass, plastic or combination glass/plastic assembly.

    摘要: Three dimensional projection systems may be single projector or multiple projector systems. These 3D projection systems may include a polarization conversion system (PCS). The PCS may be designed for relatively small throw ratios and thus, may be designed to accommodate the small throw ratios. The PCS may include a polarizing beam splitter, a first optical stack, a reflector and a second quarter wave retarder. The first optical stack may include a rotator, a polarizer, a polarization switch and a first quarter wave retarder. The PCS may receive light from a projector and the PBS may direct the light toward the first optical stack. The light may be converted to a different polarization state as it passes through the first optical stack. The converted light may then be re-directed by a reflecting element to the second quarter wave retarder. The second quarter wave retarder may convert linearly polarized light to circularly polarized light.
