| description | PROBLEM TO BE SOLVED: To provide a hologram structure that has a high forgery prevention function and security function, and has an excellent design property.SOLUTION: The present invention relates to a hologram structure that has a reflection-type Fourier transform hologram region and a transmission-type Fourier transform hologram region, where the reflection-type Fourier transform hologram region is a region to transform reflected light into a first optical image, the reflected light being light made incident from a point source and reflected on a concavo-convex surface of a first hologram layer having the concavo-convex surface on its surface, and the transmission-type Fourier transform hologram region is a region to transform transmitted light into a second optical image, the transmitted light being light made incident from the point source and transmitted through a second hologram layer arranged in a pattern.SELECTED DRAWING: Figure 1
【課題】高い偽造防止機能およびセキュリティ機能を有し、また、優れた意匠性を有するホログラム構造体を提供することを主目的とする。【解決手段】本発明は、反射型フーリエ変換ホログラム領域および透過型フーリエ変換ホログラム領域を有するホログラム構造体であって、上記反射型フーリエ変換ホログラム領域は、点光源から入射した光が、表面に凹凸面を有する第１ホログラム層の上記凹凸面で反射した反射光を、第１光像に変換する領域であり、上記透過型フーリエ変換ホログラム領域は、点光源から入射した光が、パターン状に配置された第２ホログラム層を透過した透過光を、第２光像に変換する領域であることを特徴とするホログラム構造体を提供する。【選択図】図１ |
