提出了一种新型光学接收天线的设计和制作方法, 利用干涉和衍射原理在全息材料上制成具有聚集光束和滤除环境光双重功能的全息反射镜.通过耦合波理论与k矢量闭合法分析了这种光学接收天线的角度选择性、光谱选择性以及任意点的衍射效率, 模拟结果表明: 全息反射镜在不同点的视场角和光谱带宽分别为0.8°-13.4°和4.4 nm-7.4 nm, 并且整体衍射效率在95.3%以上.与由聚光镜和滤波片组合成的传统光学接收天线相比, 全息反射镜体积小、重量轻、成本低、能作为光学接收天线用于室内可见光通信系统中.

A novel method for the design and production of the optical receiving antenna was proposed. The hologram called Holographic Mirror, which has the dual function of gathering beam and filtering ambient wave, is made from holographic material by using the principle of interference and diffraction. The angular selectivity, spectral selectivity and diffraction efficiency at any point of the novel optical receiving antenna have been analyzed by coupled wave theory and k vector closed legitimate, the results of simulation show that the field of view and spectral bandwidth at different points of the Holographic Mirror are 0.8°-13.4° and 4.4 nm-7.4 nm respectively, and the overall diffraction efficiency of more than 95.3%. Compared with the combination of a converging lens and a filter into the conventional optical receiving antenna, small size, light weight, and low cost of the holographic mirror can be used as optical receiving antenna for indoor visible light communication.
