摘要

针对大气湍流引起的激光光强、相位和传输方向的随机变化对大气激光通信质量的影响

开展了用自适应光学(AO)技术校正大气湍流影响的研究.定量分析了自适应光学技术在通信波段校正大气湍流的效果.利用中国科学院光电技术研究所研制的安装在云南丽江高美谷观测站的1.8 m望远镜和127单元AO系统

在1 550 nm通信波段对不同高度角的恒星进行了大气湍流校正实验.通过采集校正后的恒星图像

分析了校正后的斯特勒尔比

同时记录下当时的大气相干长度

由此得到了在不同大气湍流条件下的校正效果.实验表明

当大气湍流强度

即在中弱大气湍流条件下

该AO系统可以有效地对大气湍流进行校正.

Abstract

In consideration of effect of intensity scintillation

phase distortion and transmission direction changes caused by atmospheric turbulence on communication links

this paper explores the correction technology of the atmospheric turbulence by the adaptive optics (AO). The correction effects of the AO on atmospheric turbulence in the waveband of free-space communication was analyzed quantitatively. A field experiment to observe the star with different altitude angles in the 1 550 nm waveband was performed with a 1.8 m telescope mounted on Yunnan and the 127-actuators AO system developed by the Institute of Optics and Electronics

Chinese Academy of Sciences. The Strehl ratio and the atmospheric coherent length were recorded for the observation of each star. The experiment results show that when the atmospheric turbulence intensity

D/r

(1 550 nm) is less than 6.5

the wavefront error will be less than 1 rad after correction by the AO. It concludes that the AO is able to overcome the effect of the atmospheric turbulence on the required quality of free-space coherent laser com- munication under weak and moderate turbulence conditions.
