Paper Abstract

A novel method of droplet concentration measurement is presented based on analysis of angular distribution of elastic light scattering patterns, which provide a possible way to get the information of complex refractive index and inverse the liquid concentration for both absorbing and non-absorbing solutions. A mathematical model is established and an inverse algorithm corresponding to this model is also proposed which calculates the complex refractive index accurately. Experiments were carried out on both absorbing dye solutions and non-absorbing ethanol solutions with different concentrations. The results show a good agreement with the theoretical analysis and prove the potential use of this method.
