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.[...]![]()

Quiroga Mellado, Juan Antonio ; Gómez Pedrero, José Antonio ; Servín Guirado, Manuel | Taylor and Francis Ltd. | 2004-01-10A method for temporal evaluation of fringe patterns with a spatial carrier is presented. The proposed technique consists in the recording of the temporal irradiance fluctuations obtained when a linear variation of the set-up sensitivity is intro[...]![]()

Quiroga Mellado, Juan Antonio ; Estrada, Julio César ; Servín Guirado, Manuel | The Optical Society Of America | 2009-11-23We have been reporting several new techniques of analysis and synthesis applied to Phase Shifting Interferometry (PSI). These works are based upon the Frequency Transfer Function (FTF) and how this new tool of analysis and synthesis in PSI may b[...]![]()

Quiroga Mellado, Juan Antonio ; Vargas, Javier ; Belenguer Dávila, Tomás ; Servín Guirado, Manuel ; Estrada, Julio César | The Optical Society Of America | 2011-01-11A two-step self-tuning phase-shifting method is presented. The phase-step between the two interferograms is not known when the experiment is performed. Our demodulating method finds, in a robust way, this unknown phase-step. Once the phase-step [...]
