A system based on 2D Fourier transform method for accurate determination of the interference phase distribution from a sandwich interferogram with carrier fringes is presented. The technique is particularly suitable for an evaluation of surface deformation in static as well as dynamic processes. Some practical applications are shown.

Abstract
A system based on 2D Fourier transform method for accurate determination of the interference phase distribution from a sandwich interferogram with carrier fringes is presented. The technique is particularly suitable for an evaluation of surface deformation in static as well as dynamic processes. Some practical applications are shown.File in questo prodotto:
