Combinational-deformable-mirror adaptive optics system for atmospheric compensation in free space communication

Abstract As we know that deformable-mirror (DM) is used in the adaptive optics (AO) systems to compensate atmospheric turbulence in free space optical (FSO) communication system. In order to get rid of the limitations generated by the characters of DM itself, the combinational-deformable-mirror (CDM) adaptive optics (CDM-AO) system is established to correct wave-front aberrations and improve coupling efficiency at the receiver. The analysis of the principle of CDM and the decoupling-working principle based on confinement correction algorithm (CCA) is provided, and the comparison of the correcting results between CDM-AO system and conventional AO system are given. Simulation results indicate that CDM-AO system can correct different aberrations with different characteristics and provide better correction performance than single deformable-mirror (DM) AO system. And the coupling efficiency improvement provided by the correction of AO system is numerically evaluated.
