Evaluation between methods for the color measurement in holograms by using a CMOS-RGB camera and a spectrometer
(SPIE, 2013-07-22)
Many models and methods commonly used in colorimetry have been incorporated to the study and knowledge of the colorimetric properties in the reflection color holograms; these methods have reported the possibilities of color ...
Obtención de estructuras de relieve en materiales de registro de haluros de plata
(Sedoptica, 2013-09-19)
Diffraction transmission gratings were recorded in AGFA-8E75 film, chemically treated under processes with D-19 + potassium ferrocyanide and a chemical processing technique proposed for PE-2 film to obtain embossed stripes. ...
Design of a control system for interferometric fringe stabilization system with remote access
(SPIE, 2013-11-18)
Stability in a fringe pattern is a necessary condition in interferometric processes, such as holography, and not always is enough the use of passive stabilization systems, like holographic tables, in particular, when ...

Vortex metrology using Fourier analysis techniques: vortex networks correlation fringes
(OSA, 2012-10-19)
In this work, we introduce an alternativemethod of analysis in vortexmetrology based on the application of the Fourier optics techniques. The first part of the procedure is conducted as is usual in vortexmetrology for ...
In-plane displacement measurement in vortex metrology
(2013-10-09)
Recently we proposed an alternative method of displacement analysis in vortex metrology, based on the application of the Fourier optics techniques, that is suitable for an intermediate range of displacement measurements ...
Effect of the internal modulation of speckles in displacement measurements in optical vortex metrology
(SPIE, 2013-11-08)
The Optical Vortex Metrology is based on the possibility of characterizing, through topological and morphological parameters, each one of the vortices existing in the phase of the optical field, or in a pseudo-phase obtained ...
Shack - Hartmann spot dislocation map determination using an optical flow method
(OSA, 2014-01-14)
We present a robust, dense, and accurate Shack-Hartmann spot dislocation map determination method based on a regularized optical flow algorithm that does not require obtaining the spot centroids. The method is capable to ...
Novel vortex-transform for high frequency modulated patterns
(OPTICAL SOC AMER, 2013-10-07)
A novel vortex-transform is proposed. This transform allows for generating complex-valued functions from modulated intensity patterns, including high frequency components from modulation, without the generation of unstable ...
Improvement of the signal-to-noise ratio in interferometry using multi-frame high-dynamic-range and normalization algorithms
(ELSEVIER SCIENCE BV, 2012-01-01)
Using both high dynamic range (HDR) and normalization methodologies, we show a method to improve the fringe pattern contrast in interferometric measurements normally used for phase recovering. In a simulated interferogram ...
