Determination of the phase of the diffracted field in the optical domain application to the reconstruction of surface profiles

Abstract : We propose an experimental set-up working in the optical domain for determining the phase of the field diffracted by an object. We show that our apparatus can be used to reconstruct the deterministic profile of rough surfaces. We consider the particular case of diffraction gratings.
