摘要： The present application describes color management architecture for a three-panel projection system that utilizes color selective polarization filters (CSPF) and polarizing beam splitting elements (1104,1106,11089). An exemplary embodiment describes a color management architecture with a dichroic input beam splitter (1302) and three polarizing beam splitters (1104,1106,1108). An output polarizing beam splitter is used as an analyzer. The color management system architecture can isolate any color channel from those remaining whose separation and combination are then carried out by a single beamsplitting element. The disclosed embodiments also provide an improvement in the ANSI contrast. In some embodiments, an achromatic quarter-wave plate is used in combination with a color filter to block the light reflected from projection optics.

摘要： A high brightness color selective light modulator (CSLM) (10) formed by a polarization modulator (100) positioned between two retarder stacks (110, 120). The modulator (100) changes the apparent orientation of one retarder stack to the other, in a first switching state of the modulator, the two retarder stacks (110, 120) cooperate in filtering the spectrum of input light, and in a second switching state the two retarder stacks (110, 120) complement each other, yielding a neutral transmission spectrum. Two or more CSLM stages (1420-1430) can be used in series for providing independent control of a primary color. One preferred embodiment eliminates internal polarizers between CSLM stages, thereby providing an additive common-path full-color display with only two neutral polarizers (1450-1460). Hybrid filters (2225) utilize the CSLMs (1420-1430), in combination with other active or passive filters. The CSLMs (1420-1430) can be arranged in a multi-pixel array (2230), and can be implemented as color filter arrays, using patterned passive retarder instead active polarization modulators.

摘要： A system for separating light into different spectrums and for recombining the light includes at least one polarizing beamsplitter (118) and at least one retarder stack (116) configured to condition the polarization of input light differently for different spectrums. A device embodying the invention utilizes multiple polarizing beamsplitters (118, 120) and multiple reGB0001748acks (116, 126, 136). A system utilizing a single polarizing beamsplitter and a single retarder stack in combination with one or more dichroic beamsplitters (125) is disclosed. One or more reflective modulator panels (123, 127, 133) may be included to separately modulate each separated spectrum of light. Distances between the modulators and the focusing optics is essentially the same.

摘要： Beamsplitters are used in projectors with retarder stack filters to orthogonally polarize primary colors, thus converting polarizing beamsplitters to color splitters and combiners. Beamsplitters at moderate f-numbers induce geometric polarization rotations in skew rays which may degrade performance of conventional retarder stacks, resulting in color cross-talk. Retarder stacks presented herein are sensitive to the symmetries between input and output polarizer configurations. These stacks provide the polarization transformations to compensate for skew rays, such that normal incidence performance is maintained for all incident light. Systems are disclosed utilizing color selective polarization filters 'CSP' and polarizing beamsplitters without the need for an output analyzer. The CSP may be included in the above system. One exemplary CSP architecture includes two CSPs (404, 318), a single polarizing beamsplitter/combiner (324) between two (326, 330) of the three panels, and an output polarizing beamsplitter (316) element used as an analyzer such that a single CSP (318) is in the projection path. A second architecture uses an output combining chromatic polarizing beamsplitter. A third architecture uses chromatic sheet polarizers to enhance CSP performance. In all of the architectures, an output CSP and clean-up polarizer directly in front of the projection optics need not be included, thereby increasing transmission, improving imaging crispness by increasing the optical phase flatness of the projecting light, and reducing cost.

摘要： An achromatic polarization switch (APS) acts on linear polarized light to provide orthogonal polarized output states over a range of visible wavelengths. In a first switching state, the APS is operable to pass light of a first polarization state therethrough. In a second switching state, the APS is operable to transform light passing therethrough to a substantially orthogonal second polarization state. Used in conjunction with orthogonal analyzing eyewear, left and right eye images are time-sequentially modulated in orthogonal polarization states by the APS to yield a stereoscopic 3D image sensation.

摘要： Projection systems having o-plate compensation elements are described. The compensation elements may be negative, positive or biaxial anisotropic element and may have a homogeneous tilt or a splayed tilt. The compensation elements may be formed from a polymer liquid crystal. The compensation elements are designed to maximize azimuthaveraged contrast. The compensation elements may be placed an the same side of a liquid crystal panel when a micro-lens array is used to improve the ease of manufacture.

摘要： A direct view display provides a light modulating panel and a backlight including first and second sets of spectral emitters. The first set of spectral emitters generate a first light bundle and the second set of spectral emitters generate a second light bundle. Several modes of operation may be provided including (1) an advanced 2D mode, (2) an enhanced color gamut mode employing simultaneous illumination of the first and second set of spectral emitters, (3) a privacy screen mode, (4) a channel multiplexed mode, and (5) a stereoscopic image mode. The latter three modes utilize the first and second set of spectral emitters to alternately illuminate a portion of the light modulating panel. Images and representations generated by the direct view display operating in the latter three modes are viewed using appropriate eyewear having filters with passband characteristics to transmit the respective light bundle.

摘要： Disclosed are digitally-switchable bandpass filters combining non-tunable retarder stacks with switchable liquid crystal cells. The disclosed filter embodiments function like a filter wheel with no moving parts that may provide faster switching, better image registration, compact size, and lower electrical power consumption. These benefits are attractive in portable handheld devices, such as bio-hazard sensors or glucose monitors.
