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.
