Abstract

The phase fluctuations of a beam propagated in a turbulent medium are shown to depend in a nonnegligible way on the shape of the beam. Consequently, for a correct interpretation of the experiments, it is necessary not only to know the most appropriate model of the turbulence, but also to take into account the shape of the beam used in the experiments and/or the shape of the wavepath. Some examples are presented and discussed on the basis of the von Karman model of the turbulence.
