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