摘要： A diffractive display suitable for presenting graphic displays is disclosed. One embodiment includes a holographic diffraction pattern (100) carried by a permanent magnet (120) or related element and an electrically energizable coil or conductor (160) energizable for causing movement of the magnet. Rotation of the holographic diffraction pattern about a pivot (140) generates a display with diffracted light from the holographic diffraction grating. Another embodiment includes a faceted rotatable element (FRE) having an array of facets each bearing a diffraction grating and a source energizable for rotation of the FRE from a resting station to a viewing station. Rotation of the FRE generates a display from the diffracted light.

摘要： A curved surface element, for example a light bulb (16), ornament, or light pipe, has at least a portion thereof on its inner or outer surface (20) covered with a diffraction grating, for example, a holographic diffraction grating or mechanical diffraction grating, whereby such diffraction grating diffracts light to emit color to the observer. The diffraction grating can take the form of a holographic optical element (HOE) attached to the curved surface or a diffractive holographic optical pattern (HOP) embossed into the curved surface.

摘要： A method and apparatus for telecommunications applications, such as switching (Add/Drop) multiplexing and demultiplexing, is disclosed. A source (70, 72, 74, 76) of input optical signals (10) are directed onto a movable diffractive optical element or MDOE (12). Each of the optical signals is of a particular wavelength. The MDOE generates and distributes output optical signals (92, 94) among output stations (88, 90).

摘要： The present invention is directed to a diffractive display suitable for presenting graphic and the like displays. Broadly, the novel display is realized from a diffraction pattern (132) carried by (e.g. embossed) a film or element (138) connected to an energy source which is energizable for movement of the film (138). Movement of the patterned film (138) generates a display using the diffracted light from the embossed pattern (132). Electroactive films are known in the art, including, for example, piezoelectric films, electrostrictive films, electromotive films, and electrostatic films. Magnetoactive films also are known in the art. Any of these films (138) can carry the diffraction pattern (132) and be energized for movement to generate from the resulting diffracted light.
