摘      要：We propose a method for the generation of self-affine fractal random surfaces,in which we use Fourier transform and its inversion in the *** light scattering of surfaces of this kind is simulated at different incident angles of *** variation of the full width at half maximum(FWHM)of the intensity profile versus the perpendicular component k_(⊥)of the wave-vector shows clearly the characteristics of the surfaces *** simulation demonstrates how the value of FWHM at k^(2)_(⊥)w^(2)≤1 region and the slope of ln wp-ln k_(⊥)curve at k^(2)_(⊥)w^(2)≥1 region are used,respectively,to extract the lateral correlation lengthξand the roughness exponentα.
