Abstract :
A numerical simulation and an experiment on adaptive optics (AO) in 2.5Gbps laser communication system are introduced in this paper. The simulation results show that the signal fading is mitigated at a large part with AO correction. The experiment results show that the average bit-error-rate (BER) is 6 × 10-3 without AO correction. The average BER will be reduced to 1 × 10-4 with AO tip-tilt correction. And there is no bit-error in 120s with AO high order correction.
