Abstract

A novel phase Doppler method is proposed for sizing of moving spherical particles on the basis of the phase difference of two polarized beat signals in a single scattering direction. Light scattered by a moving particle is divided into two rays that are detected with different polarization angles to transmit dominantly reflected or refracted rays. The phase difference between two signals is linearly proportional to the particle diameter with a given refractive index. Numerical computations and experiments were performed to verify the usefulness of the proposed method
