摘要： PROBLEM TO BE SOLVED: To provide a rewritable optical element material capable of exhibiting the optical element function with excellent stability even when a plastic base material is used. SOLUTION: The rewritable optical element material is constituted with the plastic base material including a material which absorbs irradiation energy of laser having a pulse width of 10 -12 sec or less and is capable of forming a changeable structure part which exhibits the optical element function at least partially on the plastic base material. The changeable structure part is formed so that, when being irradiated with the laser of a pulse width of 10 -12 sec or less, the structure of the plastic base material is changed and, when being heated or being irradiated with ultra-violet ray, the structure of the plastic base material is returned to the structure before being changed and the structural change is erased. The changeable structure part can be formed at least partially and three-dimensionally on the plastic base material. COPYRIGHT: (C)2005,JPO&NCIPI
