METHOD FOR PRODUCING LIPPMANN HOLOGRAM

摘要

PROBLEM TO BE SOLVED: To enable a minute object such as micro characters to be reproduced by devising a developing method of a silver halide photosensitive material of an HI hologram, when a Lippmann hologram is recorded using an H1H2 method, thereby increasing the resolution of the Lippmann hologram, when produced as an H2 hologram.;SOLUTION: In the method for fabricating the Lippmann hologram by recording a first-stage hologram of an object T in a silver salt material 1, reproducing an object image from the first-stage hologram, disposing a photopolymer close to the reproduced object image and recording the image as a second-stage volume hologram, a developer solution containing catechol as a developing agent is used to develop the first-stage hologram.;COPYRIGHT: (C)2008,JPO&INPIT
