摘要:
The present invention is provided to enhance security of a volume hologram by recording therein individualized information such as information of character, numerical character, picture pattern, biometric matter and/or the like by irradiating laser light to the volume hologram thereby modifying the same physically or chemically, and is related to a laser marking hologram comprising a volume hologram layer 2 including interference fringes recorded therein, wherein the volume hologram layer 2 includes information of character, numerical character, picture pattern, biometric matter, and/or the like recorded therein having a contrast between an irradiated portion and a non-irradiated portion thereof provided by selectively irradiating laser light 10 to the volume hologram layer 2 in a manner to modify 11 the irradiated portion.
摘要(中):
提供本发明,通过将激光照射到体积全息图上,通过记录诸如字符,数字字符,图案图案,生物特征等的信息的个性化信息来增强体积全息图的安全性,从而在物理上或 并且与包括其中记录的干涉条纹的体积全息图层2的激光标记全息图相关,其中体积全息图层2包括记录在其中的字符,数字字符,图案图案,生物特征物质和/或类似物的信息, 照射部分和未照射部分之间的对比度是通过以修改11照射部分的方式选择性地将激光10照射到体积全息图层2而提供的。
