摘要
全息光波导（HOW）是增强现实（AR）显示的最佳解决方案，其中反射体全息光栅是核心光学元件。本研究设计并合成了5种高折射率（≈1.6）双功能丙烯酸酯单体（TPBSAs）。以tpbsa为书写单体制备了一系列两级光聚合物。其中，含有9 wt.% TPBSA-3的材料的全息记录性能最好，灵敏度高达26.59 cm mJ−1。用它作为记录介质，光漂白后的反射VHG具有高的空间频率（5634条线/ mm），衍射效率（97.14%），折射率调制（0.029），400 ~ 800 nm范围内具有良好的透明度。此外，还制作了一个能够实现虚实图像融合的HOW。
Recording Reflection Volume Holographic Gratings with Enhanced Performance by Two-Stage Photopolymers Containing Bifunctional Monomers
A holographic optical waveguide (HOW) is an optimal solution for augmented reality (AR) displays, in which reflection volume holographic gratings are core optical elements. In this study, five high-refractive-index (≈1.6) bifunctional acrylate monomers (TPBSAs) are designed and synthesized. A series of two-stage photopolymers are prepared using TPBSAs as writing monomers. Among them, one containing 9 wt.% TPBSA-3 shows the best holographic recording performance with a sensitivity as high as 26.59 cm mJ−1. Using it as the recording medium, a reflection VHG can be obtained with high spatial frequency (5634 lines per mm), diffraction efficiency (97.14%), refractive index modulation (0.029), and good transparency within 400−800 nm after photobleaching. Furthermore, a HOW capable of achieving virtual and real image fusion is fabricated.
