GENERALIZED LORENZ-MIE THEORY AND APPLICATIONS

Many optical sizing techniques rely on particle/laser interactions. The classical Lorenz-Mie theory describing sphere/plane wave interactions is therefore misleading when designing instruments and processing data when the particle size is not small enough with respect to beam diameters. In such cases the use of the generalized Lorenz-Mie theory is required. After summarizing essential features of the generalized Lorenz-Mie theory for sphere/arbitrary wave interactions, this paper describes applications of the theory with some emphasis on the analysis of phase-Doppler anemometers.
