摘要：
Holographic performances are investigated experimentally in polyvinyl alcohol/acrylamide photopolymer (PVA/AA) films with thickness of 200 mu m. Acrylamide (AA) and acrylic acid (AAc) are both used as monomers. It is demonstrated that the performances are improved due to addition of AAc monomer. The improved photopolymer shows higher diffraction efficiency and exposure sensitivity. The maximal diffraction efficiency is about 52%. At the same time, the photopolymer presents low scattering noise due to addition of AAc. The angular selectivity bandwidth of the optimum photopolymer is also measured. (C) 2015 Elsevier GmbH.
