||Sull'uso del phase shifting spaziale nella ricostruzione di campi di spostamento con tecniche ottiche
||The Spatial Phase Shifting technique makes possible to reconstruct the displacement field using the Fourier analysis of a single image. However, in its “classical” version it presents various problems—first of all the residual component of the carrier fringe field—which seriously limits its usability. This work proposes to combine some techniques, either well known, either new, with the classical spatial phase shifting algorithm so as to enlarge its working field. After illustrating these techniques and their synergic effect, a series of test problems are analyzed showing the reliability of the proposed methodology.
