摘要：

Conventional numerical methods of diffractive calculation are usually for the plane, and they are infeasible when the diffraction field applied in ICF is curved surface. In this paper, a method based on the idea of layering calculation, combining the algorithm of fast Fourier transform(FFT) with the technology of numerical fitting, has been proposed to calculate the light intensity distribution on the curved observation surface. This method can be applied to the surface with arbitrary shape, and it has comparatively high accuracy at fast calculation speed. The computation results show that the accuracy is improved as the layer number increases, and thus the method can effectively realize the light intensity distribution calculation of curved surface diffraction patterns applied in ICF.
