Abstract
The aim of this paper is to discuss the benefits as well as the limitations of utilizing photopolymer materials in the
design of holograms that are responsive to changes in their environment, such as changes in the concentration of a
specific substance, temperature, and pressure. Three different case studies are presented, including both surface
and volume phase holograms, in order to demonstrate the flexibility in the approach of utilizing holographic
photopolymers for the design of sensors and interactive optical devices. First, a functionalized surface relief hologram is demonstrated to operate as an optical sensor for the detection of metal ions in water. The sensitivity and
selectivity of the sensor are investigated. The second example demonstrates a volume transmission hologram
recorded in a temperature-sensitive photopolymer and the memory effects of its exposure to elevated temperature.
Finally, a pressure-sensitive reflection hologram that changes color under application of pressure is characterized,
and its potential application in document authentication is described.
