      Research progress on the propagation characteristics of partially coherent beam in atmospheric turbulence

      • 摘要: 光波在大气中传播时,由于大气折射率的变化,导致光强闪烁、光束扩展和光斑漂移等湍流效应,严重影响激光通信、跟踪和成像系统的性能。部分相干光受湍流影响更小,因此其传输特性成为近年来的研究热点。本文总结了国内外部分相干光在大气湍流中的传输特性研究进展,同时介绍了西安理工大学在该领域的研究工作,主要包括光强分布、光束扩展、光束漂移、光强闪烁、到达角起伏和偏振以及散斑特性等,最后对该领域的发展方向进行了展望。

         

        Abstract: When light waves propagate in the atmosphere, due to the random changes of atmosphere refractive index, turbulence effects such as scintillation, beam expansion and beam wander will be caused, which seriously affect the performance of laser communication, tracking and imaging systems. Partially coherent beam is less affected by atmospheric turbulence, which makes its propagation characteristics become a research hotspot in recent years. In this paper, the research progress of partially coherent beam in atmospheric turbulence at home and abroad is summarized, the research work of Xi’an University of Technology in this field is also introduced, including the intensity distribution, beam spread, beam wander, scintillation, arrival angle fluctuation and polarization and scattering properties, etc. Finally, the development direction of the field is prospected.
