摘要
针对自由空间光通信系统,分析了大气色散、大气湍流以及光学系统对光脉冲信号展宽的影响。给出理论分析、计算与仿真结果。证明了大气色散是引起脉冲展宽的主要因素,在某些条件下是不能忽略的。
The factors which result in pulse stretch in free-space optical communication are analyzed, including atmospheric dispersion, atmospheric turbulence influence and optical system influence. Theoretical analyses and simulating results are provided. From analyses, atmospheric dispersion is the main factor of pulse stretch, and should not be ignored under some cases.
