| Abstract: | In this paper ,the expressions for calculating axial and radial intensity distributions of the Fresnel zone plate is rigorously derived based on Helmholtz Kirchhoff diffraction integration,and numerical simulations are carried out without any approximation.The numerical results show variations of the axial and radial intensity distributions with a series of zone numbers and focal lengths. |
