摘要

自适应光学(AO)技术是缓解自由空间光通信(FSO)系统中大气湍流影响的有效途径之一，无波前探测能不依赖波前传感器直接对通信性能进行优化。对基于差分进化(DE)、随机并行梯度下降(SPGD)和模拟退火(SA)算法的无波前探测自适应光学技术在FSO 系统中的应用过程进行模拟仿真，并对比校正前后不同湍流强度下FSO 系统的耦合效率、误码率及光强起伏的变化情况，分析优化算法的畸变波前校正能力。结果表明三种算法均能有效提高FSO 系统的通信性能，DE 算法虽迭代速率较慢，但效果最优，尤其适合于强湍流情况。

Abstract

Adaptive optics (AO) technology is an effective way to alleviate the effect of turbulence on free space optical communication (FSO). A new adaptive compensation method can be used to optimize the communication performance without a wave-front sensor. The application process of the wavefront sensorless adaptive optics on FSO is simulated using the application of differential evolution (DE) algorithm, stochastic parallel gradient descent (SPGD) algorithm and simulated annealing (SA) algorithm. Meanwhile, the wavefront correction capabilities are analyzed by comparison of the coupling efficiency, the error rate and the intensity fluctuation under different turbulence intensities before and after the correction in FSO system. The simulation results show that the three algorithms can effectively improve the communication performance of FSO systems, especially the DE algorithm with lower iteration rate but optimal effects. Therefore, DE is suitable for strong turbulence conditions.
