摘要
We propose a simpli.ed model to analyse the temporary behaviour of transmittance for holographic photopolymers, based on the existing. rst- harmonic di. usion theory, with assumptions of constant polymerization coe. cient and negligible di. usion e. ect for noise gratings. By applying this model to measure real- time transmittance of our novel blue- sensitized photopolymer, the bleaching time constant of dye and polymerization rate are extracted, and the e. ect of the material composite on the noise property is revealed. This provides a prompt method to assess the performances of holographic photopolymers.
