The scattered light contains rich information about the particles. From the measured intensity and polarization of the scattered light, it is possible to extract information about the particles. Due to their rich content of information, light scattering experiments are ideally suited for tackling demanding tasks of particle anaylsis. These methods can be used to characterize soot particles, inhomogeneous sprays, dust particles, to mention only a few examples. Multiple scatterering inside a particle ensemble can be taken into account by radiative transfer calculations or more advanced techniques.
Good software is essential.
Perform accurate measurements. Most procedures to evaluate measurements do not take these dependencies into accout properly. This leads to inaccurate or completely inacceptable results. Crystalline particles often deviate strongly from spherical shape. Errors can reach up to several 100 percents.
