自适应光学技术是缓解大气激光通信中大气湍流影响的有效途径之一。建立了湍流大气激光通信的系统模型以及误码率(BER)等评价指标模型,仿真对比了各种湍流强度下发射端自适应光学校正与接收端校正对大气激光通信质量的改善效果。结果表明，自适应光学可以有效地提高接收端光功率、降低系统误码率。在收发口径为250 mm的情况下，接收端自适应光学的校正效果要明显优于发射端校正。但是，发射端校正对光强起伏有一定抑制作用，而接收端校正则不能有效抑制光强起伏。因此，从误码率的改善效果看，发射端自适应光学的作用与接收端自适应光学的作用非常接近。

Adaptive optics technology is an effective way to alleviate the effect of turbulence on atmospheric optical communication. The atmospheric turbulence optical communication system model and bit-error-rate (BER) evaluation model are established, then the difference between the transmitter adaptive optics(AO) correction and receiver AO correction working in atmospheric optical communication on different turbulence intensities is simulated. The simulation results demonstrate that AO applied in communication is beneficial for increasing the received energy of detector and decreasing the BER. Correction of receiver AO is better than transmitter AO when aperture is 250 mm. However, transmitter AO can control the intensity fluctuation while receiver AO cannot. Therefore, both transmitter AO and receiver AO have the approximate efficacy to improve BER.
