摘要： A holographic medium comprising an optical waveguide including at least one core layer positioned between portions having a lower refractive index; a diffraction grating layer formed at a boundary between the core layer and the above portions or in the core layer; and a storage layer outside the optical waveguide. An optical waveguide having the above structure in which the diffraction efficiency of the diffraction grating layer has a specific distribution is useful. In multiple-angle storage, a reference beam is emitted from an end face of a core layer or from the upper or lower side of the medium and a photodetector may be used, so as to control the incident angle. The reference beam and/or the optical waveguide is moved so that the reference beam couples only with a specific diffraction grating layer. The object beam may be focused onto a small target area of the storage layer.

摘要： An illumination panel for illuminating an object, comprising a substrate, a light diffractive grating and a light source. The substrate is made from an optically transparent material having first and second areal surfaces disposed substantially parallel to each other and a light input surface for conducting a light beam into the substrate. The light diffractive grating is mounted to the first areal surface and has a slanted fringe structure embodied therein for diffracting the light beam falling incident thereto, along a first diffractive order of the slanted fringe structure. The light source produces a light beam for transmission through the input surface and direct passage through the substrate to the slanted fringe structure so as to produce an output light beam of areal extent that emerges from either the first or second areal surface along the first diffractive order, for use in illuminating an object. A spatial-intensity modulation panel can be mounted to the illumination panel to form a color image display device. In the illustrative embodiments, the light diffractive grating is a volume hologram that is pixelated and spectrally-tuned in order to carry out spectral filtering functions within the color image display device.

摘要： An identification card provided with secret data contained in the form of a wave guide hologram recorded in a layer on the card. Light for developing or displaying the hologram is introduced into a wave guide layer extending along the surface of the card through a grating that admits light only of a given wave length suitable for developing the wave guide hologram. The secrecy of the wave guide hologram is further enhanced by incorporating into the light coupling grating a further hologram by which light only of a predetermined pattern can be coupled to the wave guide for delivery to the wave guide hologram.

摘要： A novel system and method and computer program product for exposing a photoresist film with patterns of finer resolution than can physically be projected onto the film in an ordinary image formed at the same wavelength. A hologram structure containing a set of resolvable spatial frequencies is first formed above the photoresist film. An illuminating wavefront containing a second set of resolvable spatial frequencies is projected through the hologram, forming a new set of transmitted spatial frequencies that expose the photoresist. The transmitted spatial frequencies include sum frequencies of higher frequency than is present in the hologram or illuminating wavefront, increasing the resolution of the exposing pattern. A further method is described for designing lithographic masks to fabricate the hologram and to project the illuminating wavefront. In other embodiments, a simple personalization based on Talbot fringes and plasmonic interference is performed.

摘要： A process for the production of holograms wherein only one information carrying spatial frequency is used for recording by simultaneous exposure of a light-sensitive recording material to an imagewise modulated coherent object beam and one coherent reference beam. Further a process for the reconstruction of the hologram wherein the reference beam is the inhomogeneous surface beam which is created on total reflection in the optically thinner medium of the recording layer.

摘要： An off-axis magnetic holographic record and its preparation are described. The record may be prepared, for example, by splitting the coherent beam of radiation, e.g., a pulsed laser beam, into two parts, one part impinging directly onto a magnetic recording member containing a magnetic material of low Curie point, e.g., ferromagnetic chromium oxide, the other part striking first a three-dimensional scene to be reproduced and being reflected therefrom onto the same magnetic recording member, the phase of the two parts of the laser beam being altered by the different treatments they have undergone and producing essentially an interference pattern of heat in the magnetic recording member under magnetic conditions which change the heat pattern to a pattern of magnetization. The pattern can be read out and reassembled into a three-dimensional photograph, for example, by means of a polarized light.

摘要： The invention relates to a sensor (9) comprising a hologram (17) supported on or within a holographic support medium (10). A species to be detected is reactive with a substance disposed throughout the sensor (9). Optionally, a chemical reactive with a species to be detected or a specific binding conjugate of a species to be detected is disposed throughout part of or all of the sensor (9). The resulting reaction(s) cause(s) variation(s) in the hologram (17) or holographic support medium (10) which in turn varies one or more optical characteristic(s) of the hologram (17). The variation in the optical characteristic(s) of the hologram (17) and/or the holographic support medium (10), preferably give(s) rise to a wavelength shift in incident radiation. The variation of the optical parameter is related to the species to be detected. The advantages of the sensor are that it is cheap, easy to manufacture and, once calibrated, reliable and robust.
