To reduce the effect of atmospheric turbulence and stabilize the optical link in free-space optical (FSO) communications, we have proposed to use an optical duplicate system (ODS) as a multi-beam generator. In this paper, a transmitter adopting the O

In the mini-unmanned aerial vehicle (UAV)-to-ground free-space optical (FSO) communications, bit error rate (BER) is obtained from the received power under the atmospheric turbulence by numerical calculation, and the acceptable angular range of point

To stabilize an optical link, in this study, we propose to control the focus of the received laser beam in free-space optical (FSO) communications between mini-unmanned aerial vehicles (UAVs) and ground stations. Numerical calculations confirm that t
