    摘要： This invention relates to holographic film for recording multicolor volume holograms, especially full color volume reflection holograms, and to manufacturing techniques for such film, and to corresponding methods of recording multicolor and full-color volume, in particular volume reflection holograms. We describe a holographic film for recording a multicolor volume hologram, the film comprising: a carrier; a first photosensitive recording layer sensitive to one or both of red and green laser light; and a second photosensitive recording layer sensitive to blue laser light. Both the first and second photosensitive recording layers comprise silver halide and have a grain size of less than 30 nm, and at least one of the photosensitive recording layers has a thickness of greater than 3 μm and less than 5 μm.

    摘要： A method for optical coupling comprises: includes providing a holographic recording media fixed relative to at least two optical elements; creating a hologram by transmitting light from each of the optical elements to the recording media; and transmitting light from a sending element of the optical elements through the recording media to a receiving element of the optical elements. Other variations include a system comprising at least two optical elements situated on one side of the recording media and an optical detector situated on an opposite side for detecting light transmitted through the opposite side; and a system comprising at least three optical elements situated on one side of the recording media, a beam splitter, and optical pump/control beams configured for transmitting an optical pump/control beam to the beam splitter and the opposite side so as to control transmission of an optical signal.

    摘要： A decorative foil (1) has a laminate structure comprising at least two layers (2; 3). The layers (2; 3) include a for example transparent base foil (2) which is coated on side with a reflection layer (3). A protective layer (4) can protect the reflection layer (3) from external influences. The shaping surface (7) of the base foil (2), which is towards the reflection layer (3), has a structure, obtained by shaping, of groups of geometrical shapes. An area occupied by the group is of width of between 30 &mgr;m and 300 &mgr;m. Elements (14) of the group, which are shaped in the base foil (2), are of a substantially rectangular cross-section, wherein the surface occupied by the group is composed of element surfaces (9 through 11) which are in a parallel plane (8) with respect to the shaping surface (7) and residual surfaces (13) which have remained in the plane of the shaping surface (7). The surfaces occupied by the groups are separated by regions of a background area in the plane of the shaping surface (7).
