New Method Of Deducing The Refractive Index Of Individual Aerosol Particles

This paper designs a style of particle counter which may measure the aerodynamic size and the scattering intensity of two scattering angles of the aerosol particles. The scattering intensity can also be calculated from the size and the refractive index according to the Mie theory. When the aerodynamic size is equal to the optics size approximatively, we can inverse the refractive index of individual aerosol particles by combining the relative results of the measurements.
