Basis on Mie Scattering Theory to Learn the Scattering Polarization Characteristics of Jujube in Southern Xinjiang

Abstract

As a natural product, the jujube is characterized by inhomogeneity of structure and complexity of composition. It can be regarded as a random scattering medium constructed by a large number of small tissue structures in comparison with wavelength. Based on Mie scattering theory, the equivalent random scattering medium model was studied. The variation pattern was simulated from equivalent particle size, incidence Angle and equivalent refractive index distribution. The scattering and polarization characteristics at microscale were studied. In this paper, the intensity change simulation of S component and P component at different angles and wavelengths is carried out, and the results obtained by the multi-angle scattering and spectral ellipsometer are relatively consistent. The scattering polarization characteristic of jujube was verified by spectroellipsometer. The theoretical simulation results provide important reference for further developing multi-angle polarization scattering experiment and constructing polarization scattering model to improve the precision and stability of quality detection of jujube.
