Calculating the interference fringes data with

摘要

PROBLEM TO BE SOLVED: To provide a resin for molding a computer hologram suitable for manufacturing by a 2P method with good shape reproducibility, a computer hologram and a method for manufacturing the same.;SOLUTION: The method for manufacturing the computer hologram fabricates a master disk 1 having fine rectangular patterns 1a corresponding to the shape of rectangular data for drawing based on interference fringe data. A UV curing resin 2 is then applied to a surface of the patterns 1a of the master disk 1 and after a substrate 3 is superposed thereon, the resin 2 is cured by being irradiated with UV rays, by which the resin is secured and integrated to the substrate 3. When the substrate 3 is peeled from the master disk 1 together with the cured resin layer 4, the resin layer 4 exactly transferred with the patterns 1a of the master disk 1 is formed on the substrate 3. Consequently, the computer hologram 5 having the resin layer 4 with the patterns 1a on the substrate 3 is obtained.;COPYRIGHT: (C)2004,JPO
