C.O.S. Sorzano is recipient of a Ramón y Cajal fellowship.Noise is a key problem in fringe pattern processing, especially in single frame demodulation of interferograms. In this work, we propose to filter the pattern noise using a straightforward, fast and easy to implement denoising method, which is based on a dimensionality reduction approach, in the sense of image rank reduction. The proposed technique has been applied to simulated and experimental ESPI interferograms obtaining satisfactory results.engjournal articlehttp://dx.doi.org/10.1016/j.optlaseng.2013.02.016http://www.sciencedirect.com/open access535InterferometryFringe ProcessingDenoisingDimensionality ReductionÓptica (Física)2209.19 Óptica Física
