The properties of non-spherical particles have important applications in many fields such as atmospheric sciences, oceanography, ecology, physics, optics. The study of the properties of the non-spherical particles has been the focus of international research. In this experiment, we use a new chemical method synthesis ellipsoidal non-spherical particle which a/b(horizontal and vertical ratio) is 1.6 and take this particle as the medium ,produce different concentrations of non-spherical particles in the smog chamber by using the oil mist machine, with different wavelengths of laser (532 nm, 671 nm) as the incident light under uniform conditions, through attenuation film, polarizer and 1/4 wave plate, and to rotate the polarizer to the incident light into 0 degrees, 45 degrees and left-hand polarized light. The wavelength, incident angle and the volume concentration of the non-spherical medium are taken as variables, to study the change situation of degree of polarization (DOP), polarization angle (AOP) and intensity (I), obtain the variation law of polarization transmission characteristics and the pros and cons in performance of guaranteed degree of polarization, provide data and theory for the research on the properties of the non-spherical.
