摘要
光束上行传输能量耦合效率是中继镜系统的关键因素之一,通过利用随机并行梯度下降算法(SPGD)优化出射光束的相位分布实现接收光场的光束整形,提高系统的能量耦合效率。建立了双望远镜系统模型并计算了0.10.5 m双望远镜系统垂直传输10 km和30 km的结果。结果表明,通过整形,中继镜系统的上行传输能量耦合效率得到了有效的提高。
Power coupling efficiency of beam uplink propagation is a critical factor of the relay mirror system. By optimizing the optical phase at the launching telescope, the intensity distribution at the receiving telescope can be shaped and power coupling efficiency of the two-telescope system can be improved. Model of the two-telescope system is established, results of the 0.1 ~0.5 m two-telescope system with 10 km and 30 km propagation distance are calculated. The results show that the power coupling efficiency can be significantly improved.
