摘要

Interferometers often encode the information on the measurand in the phase of a fringe pattern, which isnusually recorded by an imaging device. Accuracy of measurements carried out by interferometric techniquesnis thus strongly dependent on the accuracy with which the underlying phase distribution of these fringenpatterns is estimated. Fringe analysis methods, which have been developed to accomplish this task, are inngeneral characterized by their performance in terms of both accuracy of phase estimation and associatedncomputational complexity. We propose an improved high-order ambiguity-function-based fringe-analysisnmethod that is demonstrated to provide an accurate and direct estimation of the unwrapped phase distri-nbution in a highly computationally efficient manner. Presented simulation and experimental results in digi-ntal holographic interferometry depict the potential utility of the proposed method. © 2009 Optical Society ofnAmerica
