Propagation of superposed unpolarized beams and related discussion for acquisition of scattering potentials

Abstract

Abstract:

Two independent unpolarized light beams can sum up to be one unpolarized light beam based on the classical Stokes theory. However, it's demonstrated that its global validation needs a preliminary requirement. The work was carried out with an example of a Gaussian-Shell beam. An applicable hint was given with the determination of scattering potentials in atmospheric and biological experiments.

Key words: physical optics, partial coherence, partial polarization, free propagation, scattering potential
