An expression is derived for the mutual coherence factor for a plane electromagnetic wave propagating in a region of dielectric turbulence. It is assumed that the medium is locally homogeneous and isotropic and that the scale of turbulence l is much larger than the wavelength λ. The formula is valid within ranges L determined by assuming small scattering angles (L≪l4/λ3) and [(2π/λ)2〈(Δn)2〉lL]2≪1 where 〈(Δn)2〉 is the mean-square fluctuation of the refractive index. It is shown that this same expression can be derived within the limits of geometric optics for small separation distances.
