摘　　要：通过对自由空间光通信(FSO)系统组成原理的分析,利用OptiSystem光通信软件设计了FSO光传输链路仿真模型。在IM/DD调制方式下,结合眼图分析仪和误码率分析仪,对光链路接收性能进行分析,得到了很低的误码率,验证了无线光信号在较为恶劣天气下传输具有切实可行性。According to the analysis of FSO system composition theory,the simulation model of the FSO transmission link based on the OptiSystem software is designed.Besides,combined with the Eye Diagram Analyzer and BER Analyzer,the simulation results of transmission performance of the reception in IM/DD modulation mode are also given and deeply analyzed,very low bit error rate is obtained,the practicality of the wireless optical signal transmission in the more inclement weather is verified.
