Paper Abstract

The linear sizing technique is used to evaluate the accuracy of a new correction strategy to limit scattering matters. The ratio of the elastic scattered light with fluorescence emission over monodispersed microspheres homogenously mixed in water is measured. Three cells filled with different concentrations of these fluorescent particles are illuminated with a thin laser beam that is moved inside the cell from the front to the back. A comparison of the linear sizing technique with and without correction is presented and shows that the correction enables the measurement of higher concentrations; the limits of the correction method are also shown. These results could be a potential step to apply this technique to sprays.
