    摘要： A hologram recording apparatus is provided, including: a coherent light source; a beam splitter which splits a beam emitted from the coherent light source into a signal beam and a reference beam; a signal beam forming unit including a first optical element which splits the signal beam into a plurality of sub signal beams and deflects the plurality of sub signal beams in different directions. The signal beam forming unit further directs the plurality of sub signal beams onto a hologram recording medium. The recording apparatus also includes a reference beam forming unit which directs the reference onto a location on the hologram recording medium which overlaps with locations on the hologram recording medium on which the plurality of sub signal beams are incident.

    摘要： A device providing for microstructuring a storage medium includes a radiation source for producing an at least partially coherent beam from electromagnetic radiation, a modulator provided with a plurality of individually switchable modulator elements, a beam-forming optical element for illuminating the modulator, a reducing optical element for reducing a beam radiated by the modulator, and a transport table for displacing the storage medium in relation to the reducing optical element. The device solves technical problems caused by writing of microstructuring and individual diffractive optical elements, in particular computer-generated holograms having a high speed and high writing energy. The device is achieved in that the reducing optical element is configured with limited diffraction and produces a surface reduction of at least 25 from a surface of the individually switchable modulator elements.

    摘要： A system and method for printing a hologram are disclosed. The method includes the operation of transmitting a laser light beam. The laser light beam can be split into an object beam and a reference beam. Phase information can be added to the object beam using a spatial phase modulator to form a phase controlled object beam. The reference beam and the phase controlled object beam can be directed to a predetermined location on a holographic media to enable the reference beam and the phase controlled object beam to form an interference pattern on the holographic media.

    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.
