Originální abstrakt

On the assumption that the transmission function of a diffractive lens is periodical, the Kirchhoff diffraction integral is evaluated analytically in the paraxial region. The amplitude of the wave is expressed in terms of the infinite series which rapidly converges in the vicinity of the focal point. Hence, only a small number of terms provides an acceptable approximation of the amplitude in this region. The new formalism includes also axial locations outside the focal planes. By means of the derived analytical expressions, the image parameters (resolution, depth of field) may be related to the parameters of the diffractive lens.
