Abstract

A method to compute the diffraction field of a circularly symmetric laser beam through a sequence of circular apertures is discussed. An explicit expression of the field is given as the linear combination of a set of values of the input beam. Comparisons with numerical integration and experimental data available in the literature show its accuracy even in the Fresnel region where approximate methods such as the beam mode expansion are less accurate.
