摘要： A mechanical grating device for improving the diffraction efficiency. The mechanical grating device is built on a base having a surface. Above the base a spacer layer, having an upper surface, is provided, and a longitudinal channel is formed in said spacer layer, said channel having a first and second opposing side wall and a bottom. A plurality of spaced apart deformable ribbon elements are disposed parallel to each other. The deformable elements are organized in groups of N elements wherein N is greater than 2. When the device is actuated each of said groups forms a pattern of discrete levels wherein the pattern has n levels wherein n is greater than 2.

摘要： A method is disclosed for actuating electromechanical ribbon elements which are suspended over a channel. The channel defines a bottom surface having a bottom conductive layer formed below said bottom surface. A data generator provides a data stream. The data generator is connected to a modulator for generating from said data stream a modulated bipolar voltage signal whose time average is equal to the time average of a bias voltage applied to the bottom conductive layer. The data generator and the modulator are necessary to carry out the method. The method comprises the steps of: providing a data stream; generating from said data stream a modulated bipolar voltage signal whose time average is equal to the time average of a bias voltage applied to the bottom conductive layer; and applying said modulated bipolar voltage signal to the ribbon elements.

摘要： A color display apparatus for forming, on a display surface, a color image of superimposed color images, the display apparatus having a first color modulation channel for forming a first color two-dimensional image using a laser light source for providing a first color source beam, a linear spatial light modulator for modulating the first color source beam, and a scanning element for scanning the modulated light beam to form a first color two-dimensional image. A second color modulation channel forms a second color two-dimensional image using an incoherent light source for providing a second color source beam to an area spatial light modulator for modulating the second color source beam to form a second color two-dimensional image. A projection lens then projects a superimposed color image of the first color two-dimensional image and the second color two-dimensional image and any third color two-dimensional image.

摘要： A substantially monocentric arrangement of optical components providing a multicolor stereoscopic display having an expanded color gamut. A virtual image is electronically generated by an image generation system (70) having four or more color light sources (20) and is 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) that uses 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). The use of four or more light sources (20) provides an expanded color gamut.
