摘要： In a volumetric display (10), a strobe source illuminates a moving object (18) at successive instants separated by potentially unequal time intervals. By specifying these intervals, an illumination controller (26) achieves eye-catching visual effects suitable for advertising kiosks or other public displays. The volumetric display (10) includes a signal generator (25) configured to generate a first and second signals. An illumination controller (26) interleaves these signals and provides the resulting interleaved signals to a strobe unit that is disposed to illuminate the moving object (18) in response to the interleaved signals.

摘要： The invention features a spinning screen assembly that incorporates a thin projection screen held in place by a hollow transparent mount. The amount may be spherical in overall shape. A projection system projects portions of a 3-D image onto the projection screen. A control electronics subsystem coordinates other subsystems, including the projection system and a source of image data. Persistence of vision causes viewer to perceive a volumetric image from a series of projections. The thinness of the projection screen reduces visual dead zones. Enclosing the projection screen within the screen assembly reduces the air resistance that the thin screen is exposed to during rotation. In a further embodiment, a stationayry hemispherical transparent dome covers the spinning screen assembly.

摘要： A method of rasterizing a line on a display having pixels with locations defined by a polar coordinate system uses the sign of a discriminant to choose which of two candidate pixels is to be the next pixel on the rasterized line. The discriminant, which is derived from the desired line, is evaluated at a point in the neighborhood of the candidate pixels. The discriminant value depends on the local slope of the line in polar coordinates. The method divides the line into segments having selected ranges of slope and rasterizes the desired line along each segment.

摘要： A holographic imaging system and method includes a radiation source for generating radiation. A data base has a set of elements, each element is indicative of a trajectory of a light ray exiting a point in a recorded scene. A spatial light modulator is receptive of the radiation from the radiation source and the elements of the data base mapped to the spatial light modulator, thereby projecting from the spatial light modulator an optical signal in the nature of a two dimensional bitmap of the recorded scene. A diffractive optical element includes a set of basis fringes receptive of the projected optical signal from the spatial light modulator for diffracting the optical signal in a specified direction. A multiplexer is receptive of the elements of the data base for multiplexing the elements of the data base to the spatial light modulator. A timing device synchronizes multiplexing the elements of the data base to the spatial light modulator and diffracting the optical signal in a specified direction.
