A knowledge of some of the characteristics, for example the mean diameter, of the particles used in laser anemometry experiments is of considerable importance if the results obtained are to be interpreted with confidence. Problems associated with the determination of this quantity are discussed, relevant aspects of the scattering of light by spherical particles are briefly summarised and the results of some laboratory experiments are presented. It is shown that the seeding technique used at present, based on a commercial oil-mist generator, gives satisfactory results for most laser anemometry applications of interest to RAE. Author
