Abstract

The distribution of average intensity scattered by a plane mirror placed behind a turbulent phase screen is experimentally investigated for a point source of light. It was found that the average intensity distribution in the source plane coincides with the correlation function of intensity fluctuations of a virtual source located at the mirror and observed from the real source plane. Nonmonotonic dependence between the enhancement factor and the diameter of the mirror is observed in experiments. Experimental results are in good agreement with theoretical predictions.
