Abstract
There are exists several sources of errors in an adaptive optics system. The main source associated with the violation of the optical reciprocity principle in algorithm of phase conjugation, namely, with substitute of beacon amplitude distribution by distribution of a Gaussian beam generated by a laser. Absolute correction of turbulent aberration is possible only in case of strict maintenance of a reciprocity principle, i.e. in case of phase reversal algorithm application. In paper the possibility is considered to realize phase reversal algorithm in a linear system with the use of phase control of the beam. The system should include two mirrors separated by the vacuum gap of a finite size. Comparison of efficiency of correction on the base of phase conjugation and with the use of two mirror adaptive system were obtained.
