    Abstract: Disclosed embodiments include stereoscopic systems having at least one compensator operable to reduce the sensitivity of polarization control over incidence angle of image source optics and analyzer optics. In an exemplary embodiment, the disclosed compensator is operable to compensate polarization changes induced by optics at either or both the image source subsystem and the analyzer subsystem, in which the polarization changes would be operable to cause leakage at the analyzer subsystem if uncompensated. As such, the disclosed compensators and compensation techniques are operable to reduce leakage at the analyzer subsystem even if the disclosed compensator may be located at the analyzer subsystem.

    Abstract: Curved polarization filters and methods of manufacturing such filters are described in the present disclosure. An exemplary method includes laminating a planar polarization layer to a planar retarder layer at a predetermined orientation and bending the laminate to create a curved filter. The strain on the retarder layer results in stress-induced birefringence, and the predetermined orientation of the retarder substantially compensates for the stress-induced birefringence. In some embodiments, the predetermination is based on mathematical models. In some other embodiment, the predetermination is based on experimental data.

    Abstract: A stiffening strip at selected edges of a screen may enable the use and mounting of a high-elastic modulus substrate screen material. Such screen materials may be engineered to provide polarization-preserving characteristics, and be applied to or part of the high-elastic modulus substrate. Furthermore, the stiffening strip may enable the use of screen vibration techniques to reduce speckle in display applications that use projection screens, particularly those display applications using illumination sources prone to speckle such as laser-based projection. The screen vibration may be provided by a vibrating device attached to the stiffening strip.

    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: A method for providing a projection screen for receiving stereoscopic images may include providing a substrate with a contoured, reflective surface, wherein light reflected from the substrate substantially may undergo no more than a single reflection and may also include coating a first layer on the substrate with a contoured, reflective surface. The first layer may substantially maintain the same optical properties as the substrate without the first layer. The first layer may be substantially conformal to the surface of the substrate and also may be a self assembled monolayer coating which may include at least a functional group that is hydrophobic.
