Abstract

First order perturbation theory is used to extend Kirchhoff's approximation of thin diffraction screens and to describe surface relief structures with large modulations. The range of validity is investigated for both, the thin element approximation as well as the perturbation approach. The perturbation description is applied to the design of diffractive optical elements. Our results also illustrate the relation between the tolerance of the design against changes in the incident field and the modulation depth of the diffractive surface relief.
