Photon correlation spectroscopy is a powerful light scattering technique for studying the properties of suspensions and solutions of colloids, macromolecules and polymers. The principle of the technique is explained and the associated instrumentation is described. A number of developments in the instrumentation, which will have a substantial impact on the future application of the technique, are discussed.
