Abstract

A novel optical-digital method for interferogram processing aims at the light field phase retrieval. The method employs a Fourier-correlator with a phase sector-annular filter and the construction of the direction field and frequency field for interferometric fringes. We demonstrate that the phase is reliably retrieved if the signal-to-noise ratio is no less than one.
