    Abstract: Currently known holographic recording media and sensors have a number of disadvantages, for example, silver halide-based recording media is expensive to produce and unsuitable for use in certain sensor applications, and photopolymer- based recording media make it difficult to record multiple holographic images, thus, generally, rendering them unsuitable for use in sensors. Holographic recording media according to an embodiment of the present invention may comprise a polymer matrix and a chemical group that dimerizes by forming a cyclic bridge through photocycloaddition. These holographic recording media are cost-effective, allow recording of multiple holographic images, and enable production of sensors with controlled observable response to an external stimulus.

    Abstract: The nature of a volume hologram limits its use in security and sensing applications. Accordingly, a volume hologram (1) segregated into a first (2) and second (3) region recording a first and second image, respectively, and wherein the second region (3) 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.
