    Abstract: Two or more spectral emitters are used to provide spectrally separated light illumination onto modulating pixels of a visual display. The spectral emitters may be lasers or LEDs, typically having coherent properties. Generally, a display system includes a spectral emitter array, a light collimating element, a lens array, and a light modulating panel. The spectral emitter array includes a first spectral emitter operable to emit light of a first wavelength and a second spectral emitter operable to emit light of a second wavelength. The light collimating element is operable to direct light from the spectral emitter toward the lens array, and the lens array is operable to direct light toward the light modulating panel.

    Abstract: Shuttering eyewear used to view 3D imagery and/or dual-view images may utilize an IR receiver filter with moderate to wide bandwidth to pass data sidebands of an on-off keying signal while strongly rejecting nearby interference sources. Filtering of the signal may be achieved via a circuit for passing data sidebands of infrared signals. The circuit may include a band pass filter with a low value of Q operable to filter out a first type of interference signal from a signal, a plurality of mixers operable to receive the signal from the band pass filter, wherein the plurality of mixers down converts the signal to baseband signals, and a plurality of low pass filters operable to receive the baseband signals from the plurality of mixers, wherein the plurality of low pass filters rejects a second type of interference.

    Abstract: Methods to substantially reduce or eliminate optical non-uniformity across an interface may also substantially improve the strength and ease of seam manufacturing, including joining substrates. The methods may include managing optical non-uniformities at least by broadening a region over which a change in optical loss may occur and/or by maintaining a substantially constant average optical loss across an interface. The methods may also include forming a seam that substantially reduces the appearance of optical non-uniformities at the seam, which may include maintaining approximately constant average loss in the vicinity of the seam by substantially controlling reflectivity in the vicinity of the seam, in which substantially controlling reflectivity in the vicinity of the seam may include employing a backer treated to minimize optical reflectivity over a range of angles.

    Abstract: A polarization conversion system (PCS) is located in the output light path of a projector. The PCS may include a polarizing beam splitter, a polarization rotating element, a reflecting element, and a polarization switch. Typically, a projector outputs randomly-polarized light. This light is input to the PCS, in which the PCS separates p-polarized light and s-polarized light at the polarizing beam splitter. P-polarized light is directed toward the polarization switch on a first path. The s-polarized light is passed on a second path through the polarization rotating element (e.g., a half-wave plate), thereby transforming it to p-polarized light. A reflecting element directs the transformed polarized light (now p-polarized) along the second path toward the polarization switch. The first and second light paths are ultimately directed toward a projection screen to collectively form a brighter screen image in cinematic applications utilizing polarized light for three-dimensional viewing.

    Abstract: Generally, near seamless electronics displays may be employed in cinema and exhibition applications. Laser scanned displays may be enabled such that the display may display three dimensional (“3D”) content. A first method to enable a laser scanned display for 3D content may employ polarization, with or without polarization conversion and another method may employ multiple colors. Additionally, the envelope function that may be employed across the display may be achieved by changing laser power as a beam is scanned on the screen or by changing the dwell time of the laser beam on the pixels. One method of minimizing the effects of seams in the screen may be to reduce the screen resolution near the seams by screen design and/or laser beam dwell time or illumination energy.

    Abstract: Disclosed herein are optical projection systems and related methods for projecting imagery employing shifting image position in-time to mitigate speckle. Exemplary optical systems may include a projector having a light source, a relay lens and at least one projection lens for projecting images. The relay lens or the projection lens may have at least one lens element that may be translated in-time substantially orthogonal to the optical axis of the optical system. Alternatively, the projection lens in its entirety may be shifted in-time to reduce speckle. Further, in stereoscopic embodiments, two projection lenses may be employed, wherein at least one element in each projection lens is moveable to shift the image in-time to reduce speckle. Moreover, electronic compensation, such as electronic addressing or image warping, for the image shifting may be employed to shift the image in a direction opposite to the speckle-reducing shift in position.
