Effect of the intensity modulation on the operation of an adaptive system with an optical feedback

The effect of the intensity modulation on the operation of an adaptive system with a shearing interferometer in an optical feedback loop is studied numerically. It is shown that intensity fluctuations at the system input deteriorate the quality of compensation of phase fluctuations. The dependences of the residual compensation error on the statistical characteristics of the radiation phase and intensity fluctuations at the system input are obtained.
