摘要
为了研究新的全息记录介质, 本文我们介绍一种基于TMPTA单体的光致聚合物材料。我们已经在该聚合物薄膜样品中成功记录三维实物信息及数字静态视差图像存储等, 证明具有良好的全息记录与重建的性能。实验结果表明: 该材料在记录角度为26°时, 不加电压等任何外部条件下的衍射效率接近90%, 并且制作简便、容易保存, 作为全息记录介质能够有效地重建出高分辨率, 高衍射效率的全息再现像。由于该聚合物的高衍射效率并且不需要外加电压等特性, 该材料更加适合用于全息图和大数据的永久存储, 并且它在大尺寸静态三维全息图显示、三维图像存储、数据储存、全息防伪、全息打印等领域具有较强的优势和潜在的应用前景。
Abstract
In order to study on new hologram storage material, we introduced a TMPTA-based photopolymer in this article. We have successfully recorded three-dimensional(3D) object information and digital parallax stereogram image, etc. in this polymer film; it is shown that the polymer has a good performance in holographic recording and reconstruction. Experimental results show that a diffraction efficiency nearly 90% can be achieved when the recording angle is set to be 26° without voltage applied. As a holographic recording medium, this polymer can effectively reconstruct the wavefront information recorded in it with high resolution and high diffraction efficiency. Because of its high definition and no need of high voltage electric field, this photopolymer is more suitable for analog hologram and big data permanent storage.Our study proposes a potential holographic recording material to apply in large size static 3D holographic display, including hologram storage, digital hologram print, holographic disk and holographic anti-counterfeiting.
