Abstract: A monocentric arrangement of optical components providing stereoscopic display of a virtual image, electronically generated, line by line, from an electromechanical grating light modulator (85) and projected, as a real intermediate image, near the focal surface (22) of a curved mirror (24) by means of a scanning ball lens assembly (100). To form each left and right intermediate image component, a separate image generation system (70) comprises a scanning ball lens assembly (100) comprising a spherical lens (46) for wide field of view and a reflective surface (102). A monocentric arrangement of optical components images the left and right scanning ball lens pupil at the corresponding left and right viewing pupil (14) of the observer (12) and essentially provides a single center of curvature for projection components. Use of such a monocentric arrangement with electromechanical grating light modulator (85) as a linear image source and scanning ball lens assemblies (100) provides an exceptionally wide field of view with large viewing pupil (14).

Abstract: A method for an image-based rendering of light in a virtual volume is disclosed, which can provide various lighting effects in the two-dimensional image of a three-dimensional object. Furthermore, the virtual light source can be located at any position corresponding to the three-dimensional object. The light sources in the image are divided into two groups, i.e., the light sources in the rear of the three-dimensional object and the light sources in the front of the three-dimensional object. Then, each image for the illuminating effects of the light sources in the rear of the three-dimensional object is merged in sequence. The merged image of all of the light sources in the rear of the three-dimensional object is merged with the image of the three-dimensional object. Thereafter, each image for the illuminating effects of the light sources in the front of the three-dimensional object is merged in sequence. The merged image of all of the light sources in the front of the three-dimensional object is provided with various effects by calculation with special functions. The merged image having various effects is finally merged into the merged image of the image for the illuminating effects of the light sources in the rear of the three-dimensional object and the image of the three-dimensional object to accomplish the image-based rendering of light for the three-dimensional object.

Abstract: A method for increasing the number of intensity levels available on one or more color channels in an imaging apparatus (10) using a spatial light modulator (22). Multiple LUTs (52) are loaded into the imaging data path as data is directed to multiple spatial light modulators (22), wherein each spatial light modulator (22) has a separate bias voltage setting. In an alternate embodiment a single spatial light modulator (22) can be used with multiple LUTs (52) and with a changed bias voltage setting appropriate for use with each LUT (52).

Abstract: A 3-D viewing system is disclosed that enables multiple operators to share a common objective element while readily adjusting the orientation of images that are displayed to one or more moveable display units. The orientation of images that are displayed at a movable display unit can be made to automatically depend on the position/orientation of the display unit. Thus greater freedom in viewing postures is provided than previously available in 3-D viewing systems that share a common objective element, and each operator may view a 3-D image with proper perspective for his position/orientation. In order to reduce the number of optical components, the need to adjust optical components, and reduce costs, images from at least two different optical perspectives may be time-division multiplexed onto a single optical detecting device. Moreover, wide-angle, electronic color displays are disclosed which demodulate time-multiplexed image signals having two different parallaxes in a manner that dispenses with the need for wearing polarized glasses in order to experience a wide-angle, 3-D viewing experience. An electronic image display unit demultiplexes image data using left and right LED sets that are energized in sequence to emit up to three color light beams toward the left and right eyes of a viewer, at a frequency higher than 30 times per second. The light beams are then modulated with the image data for that color component using one or more high-speed, image modulators. Such modulators may be formed of transmissive or reflective liquid crystals in a known manner, or by an array of DMD's that are controlled in a binary fashion to reflect light for a given pixel within or outside an exit pupil of the display. If DMD's are used as the modulator, the duty cycle for a given pixel may be controlled in order to provide gradation of the display brightness for that pixel.
