| 摘 要： | 本文制备了高衍射效率的全息光栅,并对其进行了图像的可擦除存储性能研究。选用五官能度的二季戊四醇羟基五丙烯酸酯、二官能度的邻苯二甲酸二甘醇二丙烯酸酯以及向列相液晶TEB30A作为存储材料,将其置于全息干涉场中记录图像;采用He-Ne激光器实现图像的再现,并通过对全息光栅施加电场来改变光栅内液晶分子的取向,降低光栅的折射率调制度,从而使图像消失;最终得到了衍射效率为85.6%的全息光栅,通过He-Ne激光器实现了图像的再现,并在外加电场为50V时使图像基本消失,实现了图像的可擦除存储功能。

| Abstract: | Holographic grating with high diffraction efficiency was fabricated in this paper, and its erasable storage poperties were investigated. Penta-functional dipentaerythritol hydroxyl pentaacrylate, di-functional phthalic diglycol diacrylate and nematic liquid crystal TEB30A were chosen as storage materials, which could store image when put into the interference field. Image reconstruction was realized when He-Ne laser incident on the grating with Bragg angle. The image could disappear when a certain electric ... |
