El consumo de recompensas y estructuras florales por parte de las cucarachas silvestres, así como su función polinizadora en los ecosistemas naturales ha sido escasamente estudiado. El objetivo de este trabajo es describir las actividades que reali

Abstract In optics, when interferograms or digital holograms are recorded and their phase is recovered, it is common to obtain a wrapped phase with some errors, noise and artifacts such as singularities due to the non linearities of the demodulation

We present an asynchronous phase-shifting demodulation approach based on the principal component analysis demodulation method that is robust to typical problems as turbulence, vibrations, and temporal instabilities of the optical setup. The method br

Interferometry XX.
The use of the Principal Components Analysis (PCA) for recovering the modulating phase, given a sequence of Phase-Shifted Interferograms (PSI), is a very important contribution to the field. However, its verbatim translation from statistics to PSI ha

This work proposes a new algorithm for demodulating fringe patterns using principal component analysis (PCA). The algorithm is based on the incremental implantation of the singular value decomposition (SVD) technique for computing the principal value

In this paper, we present a two steps phase-shifting fringe pattern demodulation method using the VU factorization. Compared with other methods, our proposal is robust to non-constant background illuminations and modulating terms (non-normalized frin

We model a set of Phase-Shifting Interferogram (PSI) images in a new and versatile way that allows exploring interesting numerical approaches for the analysis of PSI. We show how this representation can be used to recover the modulating phase if the

The accurate recovery of an n-Dimensional field from observations that are wrapped into a particular interval (e.g., [ − π , π ] ) is a problematic step in many applications, such as holography, interferometry, optical metrology, magnetic resonan
