This paper describes a method for calculating the phase profile of digitized interferograms obtained from a phase shifting interferometer. A phase-retrieval algorithm is presented which uses total least-squares fitting of the ellipses obtained when one of the intensity profiles is plotted against the others. A propagation-of-error analysis and experimental results are also given.

Abstract
This paper describes a method for calculating the phase profile of digitized interferograms obtained from a phase shifting interferometer. A phase-retrieval algorithm is presented which uses total least-squares fitting of the ellipses obtained when one of the intensity profiles is plotted against the others. A propagation-of-error analysis and experimental results are also given.File in questo prodotto:
