The potentially more attractive techniques are based on the interaction of laser light and matter because they are capable of in situ detection of physical properties (velocity, size and concentration) of small solid or liquid particles. Moreover, very high space and time resolution may be achieved, depending on the light source, detection mode, and photo-sensor type. This paper is an overview about elastic light scattering diagnostic methods used for determination of particle size, velocity and number density in particle laden flows. No attempt, however, is made to review the very large and scattered literature. The relevant techniques are presented and discussed, with their limitations and related difficulties in both basic and applied configurations. Although the selected techniques are quite suitable for use in reacting flows, the discussion is general and not specifically directed at propulsion systems.
