title: Optical characterization and applications of a dual-cure photopolymerizable system.
abstract: The optical response of a photopolymerizable formulation consisting of a bisphenol A epoxy acrylate oligomer, a divinyl ether, and a photoinitiator system containing Rose Bengal was studied by recording holographic gratings. This blend is sensitive to blue-green light. Single- and double-exposure volume phase holograms were recorded. In addition to these examples, surface depth measurements were made by means of a holographic contour technique.
