| 摘 要： | 总结了国内外自适应光学技术在无线光通信系统应用中的研究进展和技术分类，同时介绍了西安理工大学在该领域的工作，包括有波前测量的自适应光学系统、无波前测量的自适应光学系统、液晶空间光调制器波前校正、偏摆镜和变形镜组合的波前校正、空间光光纤耦合自适应光学波前校正等。自适应光学技术可有效修正无线光通信系统中由大气湍流引起的畸变波前，提高耦合效率和通信性能。虽然这些方法在理论分析和工程实际中尚不完善，但不失为人们在该领域进行的有益探索。

| Abstract: | In chronological order, this paper summarizes the research progress and technical classification of adaptive optics technology in the application of wireless optical communication system at home and abroad. Then it introduces the work of Xi’an University of Technology in this field, including adaptive optics system with wavefront measurement, adaptive optics system with wavefront-less measurement, wavefront correction of liquid crystal spatial light modulator, wavefront correction of the combination of tilt mirror and deformable mirror, spatial optical fiber coupling adaptive optical wavefront correction, etc. The adaptive optics technology can effectively correct the distorted wavefront caused by atmospheric turbulence and improve the coupling efficiency and communication performance in wireless optical communication. Although these methods are not perfect in theoretical analysis and engineering practice, they can be regarded as useful exploration in this field. |
