The Lorenz-Mie theory [1], which is strictly valid for homogeneous spheres, is usually used as base of these techniques. However, in real sprays, due to the heating of the droplets, the real part n of the refractive index of the liquid phase changes for the reduction of its density, while the imaginary part k increase if absorbing species are formed inside the droplets [2]. In these cases the Lorenz-Mie theory is not adequate and more sophisticated models to interpret the light scattering by inhomogeneous sphere must be employed.Read More
