设计了一种椭圆抛物面结构的新型天线，用于匹配入射径向辐射光纤激光器的分布，以获得最大的传输效率。详细分析了光学天线系统在轴和离轴方向上的离焦效应，以及由此引起的能量损失。了解这些离焦量对波束发散、像差和天线传输效率的影响，对远程通信系统具有重要意义。
A novel antenna with ellipsoid-paraboloid surfaces configuration is designed for matching the incident radial radiation fiber laser distribution for maximum transmission efficiency. The on-axial and off-axial defocus effects on the optical antenna system, resulting in energy loss, are analyzed in detail. Knowledge of the effects of those defocuses on beam divergence, aberration and antenna transmission efficiency is of great importance to the long range communication systems.
