Scattering of laser radiation on density fluctuations 
in propagation of radiation through an anisotropic turbulent medium 
is analyzed. It is shown that the deviation angles in turbulent gas 
flows at atmospheric pressure equal ~10-5-10-4 
rad and can be detected by means of speckle photography.
A statistical analysis of two-dimensional fields of deviation angles
makes it possible to evaluate three-dimensional density correlation
functions in a turbulent flow. It is shown that taking account of
the turbulence anisotropy leads to distributions of the
laser-radiation intensity over deviation angles that deviate
substantially from the Gaussian distribution.
