面向无线光通信的大气湍流研究进展与展望

Research progress and prospect of atmospheric turbulence for wireless optical communication

以无线光通信为切入点,首先对大气湍流的研究进展进行了阐述,解释了大气湍流及其产生的机理与传输特性.然后分析了大气湍流所引起的光束扩展、光束漂移、光强闪烁等对无线光通信的影响.最后结合无线光通信实际,给出了作者关于抑制大气湍流的若干设想,介绍了西安理工大学在大气湍流抑制领域的实验工作.虽然该方法在理论分析和工程实际中略显不为成熟,但不失为人们在该领域所进行的有益探索.

This paper takes wireless optical communication as a breakthrough point and describes the research progress of atmospheric turbulence.The influence of the atmospheric turbulence on the wireless optical communication is analyzed from the point of the beam spread,beam drift and so on.Finally,the authors’assumption of suppressing atmospheric turbulence is given.The experimental work of Xi’an University of Technology in the field of atmospheric turbulence suppression is introduced.Although these methods are immaturity,this is meaningful exploration on the domain.
