    Abstract: PROBLEM TO BE SOLVED: To provide a hologram, which is recorded with information on deciding genuineness or spuriousness hardly observable in an ordinary observation state, is recorded with the information on deciding the genuineness or spuriousness easily observably from difference in color, when a person who decides on genuineness or spuriousness checks the information on deciding the genuineness or spuriousness, and provides high effect of preventing falsification. SOLUTION: In the hologram 10 for reconstructing a three-dimensional image, a micro object 11 which is the information on deciding genuineness or spuriousness is located behind a shielding object 12 sized, to permit easy recognition with the naked eyes. The hologram 10 is recorded with the information 11 on deciding genuineness or spuriousness, in such a manner that the information 11 on deciding genuineness or spuriousness is shielded by the shielding object 12 and cannot be observed in observation from a prescribed direction and is observable from a direction different from the prescribed direction. The hologram 10 is recorded with the information 11 on deciding genuineness or spuriousness and the shielding object 12 observably with mutually different colors. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a hologram for security where microobjects which are the information on deciding genuineness or spuriousness are arranged behind a shielding object, and the microobjects cannot be observed in the observation in a predetermined direction since they are shielded by the shielding object, and are recorded so as to be observable from the direction different from the prescribed direction.
    SOLUTION: In the method for producing a hologram for security where microobjects 2', 2'' are arranged behind a shielding object 2 sized to permit easy recognition with naked eyes, cannot be observed in the observation in a predetermined direction since they are shielded by the shielding object 2, and are recorded so as to be observable from the direction different from the prescribed direction, a hologram photosensitive material 1 is arranged on the side opposite to the microobjects 2' 2'' in the shielding object 2, the shielding object 2 is illuminated with illumination light made incident from the side 1 of the hologram photosensitive material, and the microobjects 2', 2'' are illuminated with illumination light 4' made incident from the side opposite to the hologram photosensitive material, thus they are recorded as transmission type or reflection type holograms.

    Abstract: PROBLEM TO BE SOLVED: To provide the forgery-preventive hologram which makes it possible to detect a forgery and the forgery detecting method for such a hologram. SOLUTION: The hologram is a volume type hologram 6 which has a plane or three-dimensional object image recorded and an image of a pupil 10 in fine repetitive pattern to be reproduced which can not be viewed is recorded in the actual space distant from the hologram surface at a distance from an image O" reproduction surface; and the fine pattern plate having the fine repetitive pattern which can not be viewed is arranged at a distance from the observation side of the hologram 6 and it is decided that the hologram 6 is forged when irregularity in the quantity of light is generated owing to the overlaying of a reproduced image O" with moire fringes and when no variation in the quantity of light is caused when the fine pattern plate 12 is moved a bit along its surface.

    Abstract: PROBLEM TO BE SOLVED: To provide a stereoscopic colored crest using a hologram which can not be forged by a color copy machine or a diffraction grating picture forming apparatus. SOLUTION: The stereoscopic colored crest is at least two stereoscopic linear patterns 1, 2 when being seen partially in the hologram and is reproducibly recorded and produced so as to have the parts at which at least one linear pattern of at least the two stereoscopic linear patterns 1, 2 intersects the other linear pattern on the fore side and the parts at which at least the one linear pattern intersects the other linear pattern on the back side by one point or more, respectively.
