Paper Abstract

A new method of quantitative phase evaluation of 2D fringe patterns based on Hilbert transformation is proposed. While it retains most of the advantages of the traditional Hilbert transformation method, the new method avoids the spurious discontinuities and sign reversals of the phase map from the classical Fourier-based methods. Only one interference pattern is required for the phase evaluation. The performance of the proposed method is evaluated by computer simulation.
