Paper Abstract

By employing the operator form for the solution of Helmholz equation it is a simple task to discuss the following characteristics of a diffracted wavefield: Its symmetry properties are obtained by simple inspection. The self-imaging phenomena is described in terms of the solutions of simple differential equations. The influence of focus errors is identified with some successive derivatives of the bandlimited version of the object.
