Paper Abstract

For an experiment in which a surface is scanned by a coherent beam and the scattered far field is measured, the correct mathematical tools are provided by the Gabor transform formalism. This work describes a method that uses this approach together with a parallel POCS algorithm, to reconstruct surface features. The method shows how to reconstruct a phase only object from amplitude-only data measured in a scanning experiment. An improvement of the method permits to recover frequencies lost due to the finite aperture of the optical setup.
