Abstract: The nature of a volume hologram limits its use in security and sensing applications. Accordingly, a volume hologram segregated into a first and second region recording a first and second image, respectively, and wherein the second region is responsive to stimulus while the first region is protected physically from stimulus is provided. Also provided is a volume hologram with a functional cover disposed thereon to regulate how the volume hologram interacts with the stimulus when in the presence of stimulus. A volume hologram with a removable cover disposed thereon to permit a first recorded image to be viewed, to protect the volume hologram from physical damage, to prevent the volume hologram from interacting with the stimulus, and to be removed, thereby permitting the volume hologram to interact with the stimulus is provided as well. In these ways, the usability of volume holograms in security and sensing applications is increased.

Abstract translation: 体积全息图的性质限制了其在安全和感测应用中的应用。 因此，体积全息图分别分离成记录第一和第二图像的第一和第二区域，并且其中第二区域响应于刺激，而第一区域被物理地受刺激保护。 还提供了具有设置在其上的功能盖的体积全息图，以调节当存在刺激时体积全息图如何与刺激相互作用。 体积全息图，其上设置有可移除的盖，以允许观看第一记录图像，以保护体积全息图免受物理损伤，以防止体积全息图与刺激相互作用并被去除，从而允许体积全息图 还提供与刺激相互作用。 在这些方面，体积全息图在安全和感测应用中的可用性增加。
