摘要： A method for constructing a stereoscopic light recycling device is provided. At least one support member is affixed to a beam splitter positioned at an angle and constructed of orthogonally polarizing material on which image light is received. A phase shifting optic having a reflective surface coated by a phase shifting film is positioned at an angle non-perpendicular to at least a portion of the image light from the beam splitter. The phase shifting optic includes one of a uniform and non-uniform surface.

摘要： In described examples, a method of creating multiple light images uses spatially-separated light sources, arranged in an array, operated in multiplexed fashion, for driving a spatial light modulator. Each of the light sources is time-sequenced to direct light at the spatial light modulator during a time interval. The spatial light modulator is synchronized with the light sources and controlled to produce a desired image during each time interval. The resulting images are received by an optical lens system to provide light images along an image plane. Alternately, the optical lens system focuses the modulated light images on a hogel plane to produce a light field. The pixel count of the spatial light modulator is effectively multiplied by the number of light sources.

摘要： A light-source module includes a light-source unit, a first projection lens, a first lens, a mirror wheel, a first light-guiding unit, a second light-guiding unit, and a second projection lens. The first projection lens has an entrance pupil. The light beam provided by the light-source unit can pass through the first projection lens via the entrance pupil and then is guided to the mirror wheel. With the rotation of the mirror wheel, when the light beam passes through the mirror wheel, it becomes a transmission light beam. At different time, when the light beam is reflected by the mirror wheel, it becomes a reflection light beam. The second projection lens has a first exit pupil and a second exit pupil, in which the transmission light beam and the reflection light beam pass through the second projection lens via the first exit pupil and the second exit pupil, respectively.

摘要： An image projecting system and a synchronization method for use in the image projecting system are provided. The image projecting system comprises a projector, a pair of stereoscopic glasses and a light meter. The projector projects a left-right eye test image according to a timing, and generates a plurality of left-right eye synchronization signals according to the timing. The light meter, electrically connected to the projector, measures a plurality of left-lens brightness values and a plurality of right-lens brightness values through a left lens and a right lens of the pair of stereoscopic glasses, respectively. The projector calculates a plurality of left-lens light leakage values and a plurality of right-lens light leakage values corresponding to the left-right eye synchronization signals according to the left-lens brightness values and the right-lens brightness values, respectively, so as to choose one of the left-right eye synchronization signals as an adjusted left-right eye synchronization signal.

摘要： A video controller for synchronizing presentation of a plurality of images is provided. A color switching device is operable to continually select a color out of a set consisting essentially of a plurality of fundamental colors. Each fundamental color is selected for presentation for a fixed time segment. A light processing element is operable to block and permit transmission of light in each color selected by the color switching device during each fixed time segment. The light includes at least two streams of sequential images. A synch signal generator is in control of the light processing element and is configured to time presentation of the light by the light processing element and of control signals to a viewing device of the display. The presentation of the light and of the control signals is timed in synchrony with the fixed time segments only during a transition state of the viewing device.
