Quiroga Mellado, Juan Antonio ; Villa Hernández, José de Jesús ; Servín Guirado, Manuel ; Estrada, Julio César ; Rosa Vargas, José Ismael de la | The Optical Society Of America | 2010-08-02It has been demonstrated that the vectorial fringe-direction field is very important to demodulate fringe patterns without a dominant (or carrier) frequency. Unfortunately, the computation of this direction-filed is by far the most difficult tas[...]![]()

Quiroga Mellado, Juan Antonio ; Estrada, Julio César ; Servín Guirado, Manuel ; Mosiño, Juan Francisco ; Cywiak Garbarcewics, Moisés | The Optical Society Of America | 2009-05-25We present a theoretical analysis to estimate the amount of phase noise due to noisy interferograms in Phase Shifting Interferometry (PSI). We also analyze the fact that linear filtering transforms corrupting multiplicative noise in Electronic S[...]![]()

Quiroga Mellado, Juan Antonio ; Estrada, Julio César ; Servín Guirado, Manuel | The Optical Society Of America | 2011-03-14Phase unwrapping techniques remove the modulus 2 ? ambiguities of wrapped phase maps. The present work shows a first-order feedback system for phase unwrapping and smoothing. This system is a fast phase unwrapping system which also allows filter[...]![]()

Quiroga Mellado, Juan Antonio ; Estrada, Julio César ; Servín Guirado, Manuel ; Marroquín Zaleta, José Luis | The Optical Society Of America | 2006-10-16In the last few years, works have been published about demodulating Single Fringe Pattern Images (SFPI) with closed fringes. The two best known methods are the regularized phase tracker (RPT), and the two-dimensional Hilbert Transform method (2D[...]![]()

Quiroga Mellado, Juan Antonio ; Servín Guirado, Manuel ; Estrada, Julio César | The Optical Society Of America | 2011-05-09The standard tool to estimate the phase of a sequence of phase-shifted interferograms is the Phase Shifting Algorithm (PSA). The performance of PSAs to a sequence of interferograms corrupted by non-white additive noise has not been reported befo[...]![]()

Quiroga Mellado, Juan Antonio ; Mosiño, Juan Francisco ; Servín Guirado, Manuel ; Estrada, Julio César | The Optical Society Of America | 2009-03-30Phase error analysis in Temporal Phase Shifting (TPS) algorithms due to frequency detuning has been to date only performed numerically. In this paper, we show an exact analytical expression to obtain this phase error due to detuning using the sp[...]![]()

Quiroga Mellado, Juan Antonio ; Servín Guirado, Manuel ; Estrada, Julio César ; Vargas, Javier | The Optical Society Of America | 2011-03-14In phase sampling interferometry, existing temporal analysis methods are sensitive to border effects and cannot deal with missing data. In this work we propose a quadrature filter that allows a reliable dynamic phase measurement for every sample[...]![]()

Regularized phase tracking technique for demodulation of isochromatics from a single tricolour image
Quiroga Mellado, Juan Antonio ; Servín Guirado, Manuel ; Marroquín Zaleta, José Luis | IOP Publishing Ltd. | 2002-01In this work we propose a robust fringe demodulation technique applied to the analysis of tricolour isochromatic fringe patterns produced in photoelasticity. The method used is a regularized phase tracking (RPT) algorithm, which takes into accou[...]![]()

Quiroga Mellado, Juan Antonio ; Servín Guirado, Manuel ; Estrada, Julio César ; Vargas, Javier ; Torre Belizón, Francisco Javier de la | The Optical Society Of America | 2011-10-10Any linear phase sampling algorithm can be described as a linear filter characterized by its frequency response. In traditional phase sampling interferometry the phase of the frequency response has been ignored because the impulse responses can [...]![]()

Quiroga Mellado, Juan Antonio ; Estrada, Julio César ; Servín Guirado, Manuel | The Optical Society Of America | 2010-02-01In Phase Stepping Interferometry (PSI) an interferogram sequence having a known, and constant phase shift between the interferograms is required. Here we take the case where this constant phase shift is unknown and the only assumption is that th[...]![]()

Quiroga Mellado, Juan Antonio ; Estrada, Julio César ; Servín Guirado, Manuel ; Marroquín Zaleta, José Luis | SPIE--The International Society for Optical Engineering | 2006Sequential methods like the regularized phase tracker (RPT) are commonly used for fringe pattern demodulation with closed fringes. The only drawback of the RPT method is the necessity to implement a two-dimensional (2D) fringe following scanning[...]![]()

Quiroga Mellado, Juan Antonio ; Servín Guirado, Manuel ; Cywiak Garbarcewics, Moisés ; Malacara Hernández, Daniel ; Estrada, Julio César | The Optical Society Of America | 2008-06-23It is well known that having 3 temporal phase shifting (PS) interferograms we do not have many possibilities of using an algorithm with a desired frequency spectrum, detuning, and harmonic robustness. This imposes severe restrictions on the poss[...]![]()

Quiroga Mellado, Juan Antonio ; Estrada, Julio César ; Servín Guirado, Manuel | The Optical Society Of America | 2009-09-14Systematic spectral analysis of Phase Shifting Interferometry (PSI) algorithms was first proposed in 1990 by Freischlad and Koliopoulos (F&K). This analysis was proposed with the intention that "in a glance" the main properties of the PSI algori[...]![]()

Quiroga Mellado, Juan Antonio ; Servín Guirado, Manuel ; Estrada, Julio César ; Gómez Pedrero, José Antonio | The Optical Society Of America | 2009-04-20It is well known that spatial phase shifting interferometry (SPSI) may be used to demodulate two-dimensional (2D) spatial-carrier-interfrograms. In these crises the application of SPSI is straightforward because the modulating phase is a monoton[...]![]()

Quiroga Mellado, Juan Antonio ; Gómez Pedrero, José Antonio ; Terrón López, M. José ; Servín Guirado, Manuel | Elsevier Science BV | 2005-09-15There are many phase measuring experimental setups in which the rate of temporal phase variation cannot be easily determined. In the case of phase stepping techniques, asynchronous phase measuring techniques were developed to solve this problem.[...]
