自由空间光通信（FSO）具有使高数据速率点对点传输成为可能的潜力。尽管其容量优势，自由空间光通信（FSOC）需要建立和保持视线（LOS）对准。我们考虑两个无人机（UAV），每个都有一个FSO收发器安装在一个半球形结构/头能够旋转360度~在水平面和180度在垂直面。我们提出了一种新的方案，处理的问题自动建立和维护的LOS对准的无人机与机械转向的FSO收发器之间。所提出的方法表明，使用这样的机械可操纵的收发器和一个简单的自动对准机制，它是可能的，以维持两个无人机之间的光无线链路与标称中断。
Free-Space-Optical (FSO) communication has the potential to make high data rate point-to-point transfers possible. Despite its capacity advantages, FSO communication (FSOC) requires establishment and maintenance of line-of-sight (LOS) alignment. We consider two Unmanned Aerial Vehicles (UAVs), each with one FSO transceiver mounted on a hemispherical structure/head capable of rotating 360\degree~in the horizontal plane and 180 degree in the vertical plane. We propose a novel scheme that deals with the problem of automatic establishment and maintenance of LOS alignment between the UAVs with mechanical steering of the FSO transceivers. The proposed method shows that using such mechanically steerable transceivers and a simple auto-alignment mechanism, it is possible to maintain an optical wireless link between two UAVs with nominal disruption.
