摘要： A projection apparatus (10) has an illumination section that provides first, second, and third light sources (20) for providing first, second, and third illumination beams. First, second, and third component wavelength modulating sections modulate the corresponding illumination to provide first, second, or third modulated component wavelength beams respectively. Each component wavelength modulating section uses a portion of a monochrome transmissive liquid crystal modulator panel (118) that has been segmented into at least a first, second, and third portion. A component wavelength polarizer in the path of the component wavelength illumination directs substantially polarized light to the corresponding portion of the monochrome transmissive liquid crystal modulator panel. An illumination path Fresnel lens focuses incident illumination from the component wavelength polarizer through the corresponding portion of the monochrome transmissive liquid crystal modulator panel. An analyzer (154) conditions the polarization of the modulated component wavelength beam. A lens forms an image for projection onto a display surface (40).

摘要： Filter glasses for use with a stereoscopic digital display system that displays stereoscopic images including left-eye images and right-eye images. The left- eye images are formed with light in a plurality of left-eye spectral bands, and the right-eye images are formed with light in a corresponding plurality of spectrally- adjacent right-eye spectral bands. The filter glasses include a left-eye filter and a right-eye filter, each of which includes a dichroic filter stack and one or more absorptive filter layers. Each of the filters transmits 50% or more of the light in the corresponding eye spectra bands, while providing less than 5% crosstalk. A frame is used to position the right-eye filter in front of an observer's right eye and to position the left-eye filter in front of the observer's left eye.
