论文摘要
本文以控制模式，功率效率和光束启用的方式分析了针对点对上的自由空间光学通信（FSO）方案，分析了微型摩尔阵列和相位型阵列型光学智能反射表面（OIR）。我们构建了两种类型的OIRS的物理模型。基于模型，已经得出了OIRSS输出功率密度分布和功率效率的封闭形式解决方案以及其控制算法。然后，我们提出了两种类型的OIRS的光束分裂和多光束功率分配的算法。根据分析结果讨论了FSO系统中的通道褪色和实际系统中两种类型的OIRS的比较。提出了实验和模拟，以验证模型和算法的可行性。
Oriented to the point-to-multipoint free space optical communication (FSO) scenarios, this paper analyzes the micro-mirror array and phased array-type optical intelligent reflecting surface (OIRS) in terms of control mode, power efficiency, and beam splitting. We build the physical models of the two types of OIRSs. Based on the models, the closed form solution of OIRSs' output power density distribution and power efficiency, along with their control algorithms have been derived. Then we propose the algorithms of beam splitting and multi-beam power allocation for two types of OIRSs. The channel fading in FSO system and the comparison of two types of OIRSs in actual systems are discussed according to the analytical results. Experiments and simulations are both presented to verify the feasibility of models and algorithms.
