摘要/Abstract

摘要： 研制了一种新型全息用光致聚合物材料,其成膜树脂为胺固化环氧体系,全息记录组分为光引发自由基聚合体系.用新合成的高效光敏染料DEAMC做光敏剂,通过配方调整,制备了一系列的样片,以457 nm的蓝光为记录光,632.8 nm的红光为探针光,研究了样片的衍射效率、灵敏度、折射率调制度等全息性能.结果表明,通过调整材料的配方组成、各组分的含量及样片的膜厚等因素,可以优化样片的全息性能.对样片的信噪比损失(LSNR)测试结果表明,在全息存储的曝光量范围内对样片曝光引起的图像信噪比损失仅有0.40 dB,说明样片的光学质量高,在全息存储上将具有很好的应用前景.

关键词: 全息存储, 光致聚合物, 环氧树脂

Abstract: Novel photopolymers for holographic storage were investigated by combining acrylate monomers as recording media and liquid epoxy resins plus an amine harder as binder.A series of samples were prepared using a newly synthesized dye DEAMC as sensitizer and their holographic properties,such as diffraction efficiency,sensitivity,and refractive index modulation were studied by two 457 nm laser beams as record beams and a 632.8 nm laser as probe beam.The results indicated that samples’ holographic properties were affected significantly by component and thickness of samples.Measurements of image quality through the samples were carried out,and the loss of signal-to-noise ratio(LSNR) as low as 0.4 dB was obtained.This indicates that these materials would be promising for high-density holographic storage.

Key words: holographic storage, photopolymer, epoxy resin
