Research On The Scattering Of Normal Incidence Surface Of Cone

The cone is divided into facets and each of the facets was analyzed with Lambert scattering distribution. The scattering of rotating ellipsoid was detailed analyzed and the scattering model of rotating ellipsoid deduced at normal incidence. At the same time, the applied model of the scattering was set up and the simulation was carried out with different contour parameters at normal incidence, and the laser scattering curves were plotted. The results show that the scattering light intensity achieve the maximum value when the zenith angle equals to 0 degree and decreases as zenith angle increasing, when the zenith angle equals to 180 degree the scattering light intensity close to zero. The further analysis shows that the scattering light intensity distributes smoothly when the ratio of long and short half axis is small but distributes more and more acute as the ratio of long and short half axis gets greater.
