Diffraction efficiency of photopolymers: use of Gaussian recording beams and real-time monitoring

A measurement technique making it possible to obtain dynamical recording characteristics of photopolymer materials, i.e. the diffraction efficiency versus exposure time and irradiance, from a single holographic exposure using Gaussian recording beams is presented. The material under investigation is the DuPont photopolymer solution HRS- 150X001-20-35.
