HOLOGRAM RECORDED WITH INFORMATION ON DECIDING GENUINENESS OR SPURIOUSNESS

摘要

PROBLEM TO BE SOLVED: To provide a hologram which is recorded with information on deciding genuineness or spuriousness hardly observably in an ordinary observation state and provides a high effect of preventing forgery.

SOLUTION: The hologram 10 for reconstructing three-dimensional images is arranged with microobjects 11 which are the information to decide authenticity behind shielding objects 12 sized to permit easy recognition with naked eyes and is recorded with the information on deciding genuineness or spuriousness in such a manner that the information on deciding genuineness or spuriousness is shielded by the shielding objects 12 and cannot be observed in the observation in a prescribed direction and are observable from the direction different from the prescribed direction.
