OPTIMAL WAVELENGTH SELECTION ALGORITHM OF NON-SPHERICAL PARTICLE SIZE DISTRIBUTION BASED ON THE LIGHT EXTINCTION DATA

Abstract

In this paper, the anomalous diffraction approximation method is improved for alculating the extinction efficiency of non-spherical particles. Through this step, he range of the refractive index of particles can be enlarged, and the improved nomalous diffraction approximation method can be applied easily to the calculation f extinction efficiency for the most kinds of non-spherical particles. eanwhile, an optimal wavelength selection algorithm is proposed for the inversion f non-spherical particle size distribution in the dependent mode. Through he improved anomalous diffraction approximation method, the computation time s substantially reduced compared with the rigorous methods, and a more accurate nversion result of particle size distribution is obtained using the optimal avelength selection method.
