    摘要： A holographic recording medium in which information can be reproduced by phase conjugate beam without requiring a mirror for obtaining the phase conjugate beam and its driving part and recording density is not reduced. The recording medium includes a recording layer in which an interference pattern is recorded and a light absorption/transmission layer which can be reversibly changed to be in a first state where signal beam and reference beam passed through the recording layer are absorbed at the time of recording of information and a second state where the reference beam is transmitted at the time of reproduction of information, and the reference beam transmitted through the light absorption/transmission layer is reflected by a reflection layer to produce the phase conjugate beam.

    摘要： A thermosensitive ink layer 102 is composed of a thermochromic material which changes from black to a transparent state and is formed on a substrate 101 made from a PET film by heating. A cholesteric liquid crystal layer 103 on which a hologram 105 of an appropriate form is formed on the cholesteric liquid crystal layer is mounted thereon. At ordinary temperature, the thermosensitive ink layer 102 exhibits a property of light absorption and a property of selective reflection and a color shifting of the cholesteric liquid crystal layer 103 are observed. The thermosensitive ink layer 102 becomes transparent by heating and the figure 104 on the substrate 101 is also visible. The determination of the authenticity thereof is performed by utilizing the change of view. Therefore, the anticounterfeiting effects are superior to those of the discrimination techniques using conventional techniques, and this enables articles to be distinguished easily and reliably.
