摘要： A small, inexpensive three-dimensional image display having a structure for displaying a color three-dimensional image sharply even if a low-resolution spatial optical modulating element is used. The three-dimensional image display has an illumination light source unit, a transmission spatial optical modulating element, a lens, and a mask. The illumination light source unit includes three point light sources outputting illumination light components having wavelengths (red, green, blue) different from one another. The point light source outputting the blue illumination light component of the shortest wavelength is disposed in position B (0, 0) on the optical axis of an illumination optical system, the point light source outputting the red illumination light component is disposed in position R (xr, 0), and the point light source outputting the green illumination light component is disposed in position G (xg, 0). An aperture section of the mask is disposed in the region where the zero-order diffracted waves of the reproduction light components of the three wavelengths after subjected to wavefront conversion by the lens are superposed on one another. The illumination optical system determines the direction of incidence of each of the illumination optical components of the three wavelengths on the spatial optical modulation element.

摘要： The present invention relates to a compact and inexpensive 3D image display apparatus and others with a structure enabling color display of a clear 3D image even with use of a spatial light modulator of a low resolution. The 3D image display apparatus has an illumination light source section, a transmission type spatial light modulator, lenses, and a mask. The illumination light source section has three point light sources for emitting illumination light components of mutually different wavelengths (red, green, and blue). The point light source for emitting the blue illumination light component of the shortest wavelength is located at the position B(0,0) on the optical axis of an illumination optical system, the point light source for emitting the red illumination light component at the position R(x r ,0), and the point light source for emitting the green illumination light component at the position G(x g ,0). The mask is provided with an aperture in an area in which zero-order diffracted waves of respective reproduced light components of the three wavelengths are superimposed on each other after wavefront transformation by the lens. For implementing it, the illumination optical system sets incident directions of the respective illumination light components of the three wavelengths to the spatial light modulator.

摘要： A system for the production of a dynamic image for use in holography includes a light source (16) which travels via a liquid crystal modulator (18) placed in the path of the light source (16). The output of the LC modulator (18) passes modulated light through a lens array (22) which itself guides light to an optically addressed spatial light modulator (24). The resulting real image from the optically addressed spatial light modulator (24) may be used in holography. The addressing frame-rate of the liquid crystal modulator (18) is substantially greater than the frame-rate of the optically addressed spatial light modulator (24).

摘要： A procedure for displaying Diffraction Specific (DS) Computer Generated Holograms (CGH) includes the provision of a novel diffraction table (DT) modified so as to store a complete decoded fringe for each point capable of being projected into the image volume. When generating a DS CGH the diffraction table is produced that holds data relating to the image to be projected. The prior art stores in this diffraction table a set of hogel vectors that are used to select a set of basis fringes relating to each point to be displayed on the CGH. This means that each basis fringe corresponding to a particular hogel vector must be accumulated together with all the others before a complete fringe is produced. The pre-computation of the fringes as per the current invention singificantly reduces the online processing requirements of producing an image, as the new DT can be produced offline with no knowledge of the image to be displayed.
