Abstract Haze has seriously affected the people’s daily life. By detecting the polarization information of the scattered ultraviolet light of haze particles, the causes of haze can be effectively analyzed. Small-scale surface roughness is a morphological feature that is obtained from mineral and dust particles in haze, therefore Chebyshev particle modelcan be used to knowthe haze particles. The “solar blind” ultraviolet light will be scattered due to the Chebyshev haze particles. The polarized properties of the scattered light can invert the physical properties (such as particle size parameters, complex refractive index, particle deformation, ripple parameter) of the Chebyshev haze particles. This paper has used the ultraviolet single scattering model and T matrix method to analyze the relationship between the physical properties of Chebyshev haze particles and the ultraviolet light polarization properties (Stokes vector and the degree of polarization). The results show that the particle size has a great influence on the change trend of the scattered Stokes vectorIsand Qs with the scattering angle. The change of the particle size and the imaginary part of the particle complex refractive index caused the degree of polarization the scattered light changed with the scattering angle. Meanwhile, the article has been specifically analyzed the effect of the Chebyshev particle size on the scattered light Stokes vector Is and Qs is the largest when the scattering angle is 10°. And when particle size r<1 μm, the change of Is with particle size shows a parabolic trend. When the deformation of the Chebyshev particle isincreased, the scattered Stokes vectorIspresents increased initially and then decreased.
