Primary Means

Adaptive optics (AO) is the primary means of improving the light transmission quality and easing the optical turbulence in communication. In laser intensity/direct demodulation (IM/DD) optical communication system, the function of AO correction for improving the optical communication performance is analyzed, adaptive optics (AO) compensating effects of atmospheric turbulence is studied by simulation and experiment in our adaptive optics system test bed. And 2.5 GB/s optical communication system performance is improved by AO compensating effects. So signal noise rate (SNR) and bit error rate (BER) of laser communication are improved.

Beam Transmission

Sixty-one unit adaptive optical system was used to analyze the influence of atmospheric turbulence on laser beam transmission in space laser communication system. From low earth orbit planet to ground station Laser communication system was estimated by means of optical design software. In addition, the compensation results, experimental phenomena and data based on adaptive optics were also analyzed in the paper.
