通过仿真和实验研究了利用光束发散度控制来减小基于OAM的自由光通信链路中的角度误差效应。结果表明，控制光束发散角可以降低功率损耗和角度误差引起的信道串扰。
Using beam divergence controlling to mitigate angular error effects in OAM-based FSO links is investigated through simulation and experiment. Results show that controlling beam divergence allows reducing power loss and angular error induced channel crosstalk.
