Investigation of 1064nm laser scattering characteristic in atmosphere by means of improved Mie algorithm

To study the scattering characteristic of 1064nm laser in low latitude,improved Mie scattering algorithm was put forward,in which the iterative function was simplified to reduce the storage array, and the endless circulation was truncated to reduce the number of circulation.From the simulation, the distribution of single and bulk scattering was obtained and it was found that the scattering distribution was focused in forward scattering at a small angle, and that the scattered laser might be absolute polarized light.The results show that the new method embodies the advantage of fast convergence and high precision.
