在本文中，我们展示了一种动态全息显示在量子点(ZnS/InP)掺杂的液晶器件中，其中一个内单元表面被一层ZnSe覆盖。这种混合器件的光折变灵敏度显著提高，达到2.2 cm(3)/J，几乎是不含锌硒层的掺锌/铟掺杂液晶器件的300倍。全息光栅可以在类似于0.8 mW/cm(2)的低强度下形成，并表现出几到几十毫秒的快速光学响应。利用该器件的感光性能和快速响应特性，我们获得了红、绿、蓝三种颜色的动态全息视频，以及高灰阶保真度的再现图像。(C)2016年度美国光学学会
In this paper, we demonstrate a dynamic holographic display in a quantum dot (ZnS/InP) doped liquid crystal device, where one of the interior cell surfaces is covered by a ZnSe layer. Such a hybrid device shows substantially improved photorefractive sensitivity of 2.2 cm(3)/J, which is almost 300 times larger than that in ZnS/InP doped liquid crystal device without the ZnSe layer. The holographic grating can form at intensities as low as similar to 0.8 mW/cm(2), and exhibit a fast optical response of several to tens of milliseconds. Exploiting the superior performances of photosensitivity and fast response of this device, we obtain dynamic holographic videos of red, green, and blue colors, as well as a reconstructed image of high gray-scale fidelity.
