Abstract : This report is a detailed summary of three lectures concerning the coherence properties of radiation passing through a random medium such as the atmosphere. These lectures consisted of a review of the basic work in the field and a discussion of transient effects, some new work on propagation developed by the author and discussion of a formal method of analysis that allows one to assess the effects of a random medium on a photographic image. The report gives an approximate solution for the development of the mutual coherence function as it propagates through statistically homogeneous and isotropic random media. Only small-angle scattering about the principal propagation direction z is considered.
