| Zusammenfassung: | There are provided volume holograms and combinations of lenticular lenses and holograms in particular for security apllications. In embodiments, a volume hologram comprises a holographic medium (102)including a first optical interference structure which, upon illumination, replays a first image (110); wherein the first image includes a lenticular lens layer (111) including an array of lenticulesand a lenticular image layer (113) including first (114) and second (115) interlaced images corresponding with the array of lenticules.
本申请提供了体全息图以及双凸透镜和全息图的组合，尤其用于安全性应用。在实施例中，体全息图包括全息介质(102)，其包括第一光学干涉结构，该第一光学干涉结构在光照射时再现第一图像(110)；其中第一图像包括双凸透镜层(111)和透镜图像层(113)，该双凸透镜层(111)包括微透镜阵列，该透镜图像层(113)包括与微透镜阵列相对应的第一交错图像(114)和第二交错图像(115)。 |
