Improvement on Spatial Resolution and Photosensitivity of Red-sensitive Photopolymer for Holographic Applications
By employing low molecular-weight polyvinyl alcohol as binder, the spatial resolution of a red-sensitive Polyvinyl Alcohol/Acrylamide based photopolymer are improved from 1000 lines/mm to 3000 lines/mm, and the photosensitivity is also increased about 5 times by increasing the ambient temperature during the holographic recording. Our optimized photopolymer system has high-quality holographic recording characteristics such as high spatial resolution (over 3000 lines/mm), high photosensitivity (8 mJ/cm2) and high diffraction efficiency (over 94%). Some preliminary applications of using the photopolymer for holographic interferometry and holographic storage are also given in this paper.
