Improving the Angular Visibility of Photopolymer-Based Reflection Holograms for Sensing Applications

Improving the Angular Visibility of Photopolymer-Based Reflection Holograms for Sensing Applications

Volume reflection hologram-based sensors are designed to visibly change colour in response to a target stressor or analyte. However, reflection holograms fabricated in thick photopolymer films are highly angularly selective, making these sensors challenging to view and interpret by non-experts. Here...
