我们提出了三维（3D）图像和数据的全息存储在光聚合物薄膜中，没有任何外加电场。测量了它的吸收和衍射效率，并记录了真实物体的反射模拟全息图和数字信息的图像。将光聚合物与聚合物分散液晶作为全息材料进行了比较。除了前者的全息衍射效率略低于后者外，本工作还表明，该光聚合物具有高清晰度，无需高压电场，更适合于模拟全息和大数据永久存储。因此，我们的研究提出了一种潜在的全息存储材料，可应用于大尺寸静态3D全息显示器，包括模拟全息图显示器、数字全息图印刷品和全息磁盘。
We present holographic storage of three-dimensional (3D) images and data in a photopolymer film without any applied electric field. Its absorption and diffraction efficiency are measured, and reflective analog hologram of real object and image of digital information are recorded in the films. The photopolymer is compared with polymer dispersed liquid crystals as holographic materials. Besides holographic diffraction efficiency of the former is little lower than that of the latter, this work demonstrates that the photopolymer is more suitable for analog hologram and big data permanent storage because of its high definition and no need of high voltage electric field. Therefore, our study proposes a potential holographic storage material to apply in large size static 3D holographic displays, including analog hologram displays, digital hologram prints, and holographic disks.
