Abstract

The coherence length for propagation of radiation through a turbulent medium is a measure of the phase distortion of the wave by the turbulence. It is expressed in terms of an integral over the propagation path of the atmospheric refractive-index structure constant $C_N^2$. For a commonly used parametrization of dependence of $C_N^2$ on height, this integral is evaluated analytically.
