Abstract
A new technique based on the polarized phase detection of optical beat signals is proposed for size analysis of moving spherical particles. Light scattered by a particle in the two-beam intersection is divided into two rays and detected with different polarization angles. The phase difference between two beat signals can be used for particle size analysis. Numerical computations of the Mie theory and experiments were performed to verify the usefulness of the proposed technique.
