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： A stereoscopic digital projection system that projects stereoscopic images including first-eye images and second-eye images. The system includes one or more narrow-band, solid-state, tunable light emitters, each being controllable to alternately provide emitted light in a first state in a corresponding first spectral band and emitted light in a second state in a corresponding second spectral band. An image forming system including at least one spatial light modulator is used to form modulated images by modulating light from the tunable lights emitters. A controller synchronously controls the state of the tunable light emitters and the spatial light modulator pixels, wherein the spatial light modulator pixels are controlled responsive to first-eye image data when the tunable light emitters are in the first state and are controlled responsive to second-eye image data when the tunable light emitters are in the second state.

摘要： A projection apparatus for producing color images having reduced speckle artifacts comprising: at least three narrow band light sources having first, second and third visible wavelength bands; a digital image source providing color digital image data; at least one spatial light modulator for forming a color image using light responsive to the color digital image data; a projection display surface including a reflective layer that reflects incident illumination in the first, second, and third wavelength bands; and a fluorescent agent that absorbs a fraction of the incident light in the first visible wavelength bands and emits light in a corresponding first emissive visible wavelength band; and a projection lens that projects the color image onto the projection display surface; wherein return light from the projection display surface contains light in both the first incident visible wavelength band and the first emissive visible wavelength band, thereby reducing speckle artifacts.

摘要： A beam alignment system for generating an aligned two-dimensional array of parallel light beams, comprising a beam alignment chamber including a base extending in a length direction and a plurality of reflectors mounted on the base, each having independent yaw and pitch adjustments. The beam alignment system further includes a plurality of arrays of light sources, each generating an array of light beams and being paired with a corresponding reflector, the reflectors being disposed to direct the light beams along the length of the beam alignment chamber forming an aligned two-dimensional array of parallel light beams.
