Abstract:
(EN) Provided are an optical element, a laminate body, and a book form having improved security. The optical element 40 is equipped with a hologram layer 41 on which a hologram image 41b is recorded, and a diffraction grating layer 50 laminated under the hologram layer 41. The diffraction grating layer 50 is equipped with a diffraction grating 52a having recesses and protrusions in the thickness direction. In addition, a card 1 is equipped with this optical element 40.
(FR) L'invention concerne un élément optique, un corps stratifié et une forme de livre présentant une sécurité améliorée. L'élément optique (40) est équipé d'une couche d'hologramme (41) sur laquelle une image d'hologramme (41b) est enregistrée, et d'une couche de réseau de diffraction (50) stratifiée sous la couche d'hologramme (41). La couche de réseau de diffraction (50) est équipée d'un réseau de diffraction (52a) ayant des renfoncements et des saillies dans la direction de l'épaisseur. En outre, une carte (1) est équipée de l'élément optique (40) selon l'invention.
(JA) セキュリティ性を向上した光学要素、積層体、冊子体を提供する。 光学要素40は、ホログラム画像41bが記録されたホログラム層41と、ホログラム層41の下側に積層された回折格子層50とを備え、回折格子層50は、厚さ方向に凹凸を有する回折格子52aを備え、また、カード1は、この光学要素40を備える。
