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. Propagation of error analysis and experimental results are also given.

Retrieval of the phase profile of digitized interferograms

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. Propagation of error analysis and experimental results are also given.
