The close circumstellar environment of Betelgeuse IV. VLTI/PIONIER interferometric monitoring of the photosphere
(ESO, 2016)
Context. The mass-loss mechanism of cool massive evolved stars is poorly understood. The proximity of Betelgeuse makes it an appealing target to study its atmosphere, map the shape of its envelope, and follow the structure ...
Interferometric Mapping of Magnetic Fields: The Massive Star-forming Region G34.4+0.23 MM
(2008)
We report millimeter interferometric observations of polarized continuum and line emission from the massive star forming region G34.4. Polarized thermal dust emission at 3 mm wavelength and CO J=1→0 line emission were ...
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 ...

Analysis of vibrations in a plate using interferometric methods
(SPIE-INT SOC OPTICAL ENGINEERING, 2004-01-01)
In this work some frequencies and modes of vibration of a thin plate were determined using interferometric methods like: real-time holographic interferometry, time-average holographic interferometry, digital speckle pattern ...
Temporal evolution of sulfated zirconia sol-gel during dip coating: Analysis of mass drainage with time-varying refractive index
(2006-12-01)
The formation of sulfated zirconia films from a sol-gel derived aqueous suspension is subjected to double-optical monitoring during batch dip coating. Interpretation of interferometric patterns, previously obscured by a ...
