Abstract:The phase calculation is a powerful measurement technique that allows the reconstruction of 3D profiles from interferograms intensity. Among the methods commonly used for the phase calculation, there are the Fourier method, the phase shift method and the wavelet method. This research is based on the phase extraction from a single uncarrier interferogram using HHT technique (Hilbert Huang Transform). Here, we present a phase calculation algorithm based on the BEMD method (Bidimensional Empirical Mode Decomposit… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
