    摘要: A method of recording a volume holographic image is described in which a holographic recording medium containing a photoreactive dye is exposed to a plurality of coherent light sources emitting at a wavelength to which the dye is sensitive, thereby forming an interference fringe pattern therein. The photoreaction occurring in the areas of constructive interference generates a periodic array of photoreacted areas of the dye and unreacted areas of the dye. This generated interference fringe pattern may contain, but does not have to contain any image or other encoded information. Selected areas of the interference fringe pattern are then exposed to actinic radiation in such a manner to partially or fully bleach, remove, or deactivate the photoreactive dye fringe pattern, thereby producing a holographic pattern, shape, or image formed by areas of the interference fringe pattern that were not bleached, removed, or deactivated.

    摘要: A method is described for recording a volume reflection holographic image that is viewable when illuminated by light at a wavelength Wv. The method includes providing a transparent holographic recording medium having a refractive index n, said holographic recording medium being photosensitive to external light provided at a wavelength W that is different than Wv; disposing a first transparent refracting medium in contact with a first surface of the holographic recording medium; and exposing the holographic recording medium to a signal coherent light source that includes image or other information to be recorded in the holographic recording medium and a reference coherent light source, the signal coherent light source and reference coherent light source emitting light at the wavelength W and entering the holographic recording medium through opposing surfaces thereof, wherein the signal coherent light source or the reference coherent light source passes through the first transparent refracting medium before entering the holographic recording medium at an internal angle of incidence greater than arcsin(1/n).

    摘要: A method of recording a holographic record is described. According to this method, a holographic recording medium is exposed to a desired pattern, shape, or image from a coherent light source emitting light at one or more wavelengths to which the holographic recording medium is sensitive. In this method, light having the desired pattern, shape, or image to which the holographic recording medium is exposed is diffracted by a spatially homogeneous optical diffraction element so that the holographic recording medium is exposed to a plurality of interfering light beams, thereby forming a holographic record in the holographic recording medium. Holographic recording articles are described that include a holographic recording medium and a spatially homogeneous optical diffraction element.
