The methods used in the application of light scattering to the study of thermally excited capillary waves on liquid surface or interfaces are reviewed. The focus is on the use of photon correlation to determine the spectroscopic information carried by the scattered light. Particular attention is directed to extraction of the maximum amount of information from the data, including surface viscoelastic parameters and intensities.
