摘要： A method for forming a stereoscopic image forms separate left-eye and right-eye images in a repeated cycle that forms the left-eye image by providing data for lines of the left-eye image, ordered in sequence from a first to a second edge of an image frame, then forms successive lines of modulated light according to the ordered sequence by progressively scanning lines of modulated light across a display surface by rotating a scanning element forward from a first to a second position. The right-eye image is formed by providing data for lines of the right-eye image, ordered in sequence from the second to the first edge of the image frame and forming successive lines of modulated light, progressively scanning the lines of modulated light across the display surface by rotating the scanning element in reverse from the second to the first position. The left-eye image is distinguished from the right-eye image.

摘要： A digital projection apparatus has a first light modulation subsystem with a first light source producing linear illumination of a first spectral color and a second light source producing linear illumination of a second spectral color. A first light modulator chip (110a) has at least two independently addressable linear arrays of light modulating devices. A first spatial filter (108) blocks reflected light and transmits diffracted light along a first optical path. A second light modulation subsystem has at least a third light source producing linear illumination of a third spectral color. A second light modulator chip has at least one independently addressable linear array of light modulating devices. A second spatial filter blocks reflected light and transmits diffracted light along a second optical path. A color combining element directs modulated light onto a common optical path. Projection optics direct modulated light toward a scanning element (122) for projection toward a display surface (124).
