Near-field characteristics of periodic surface relief diffraction structures from far-field measurements

Abstract Near-field characteristics of periodic surface structures, i.e. their surface relief, may be determined by measuring the diffraction efficiency, i.e. from far-field measurements, if the relief is described by a known periodic function with a few unknown geometric parameters. This method is formulated for one- and two-dimensional periodic structures and demonstrated for some holographic grating structures.
