Reprocessing of data from Fabry-Perot interferometers (FPI) belonging to the IGP network of optical instruments

Barbaran Meza, J.; Rojas, R.; Navarro, L.; Veliz, Oscar; De la Jara, César; Milla, Marco (Instituto Geofísico del Perú, 2021-06)

IGP network of optical instruments consist of two types of imaging instrumentation: Fabry-Perot Interferometers (FPI) and All-Sky imagers (ASI). The FPI can obtain two dimensional interferograms that are used to study the ...

Double domain wavelength multiplexed Fizeau interferometer with high resolution dynamic sensing and absolute length detection

Antonacci, Julian; Arenas, Gustavo Francisco; Duchowicz, Ricardo (Elsevier, 2017-04)

In this work, we present a simple photonic instrument that has the ability of measuring positions, distances and vibrations with very high resolution by means of two Fizeau interferometers (FI), both using the same optical ...

Simple and versatile heterodyne whole-field interferometer for phase optics characterization

SILVA, D.M.; BARBOSA, E.A.; WETTER, N.U. (2012)

First light for GRAVITY: phase referencing optical interferometry for the very large Telescope Interferometer

Abuter, R.; Accardo, M.; Amorim, A.; Kervella, P. (EDP Sciences, 2017)

GRAVITY is a new instrument to coherently combine the light of the European Southern Observatory Very Large Telescope Interferometer to form a telescope with an equivalent 130m diameter angular resolution and a collecting ...

Analysis of linearity and frequency response of a novel piezoelectric flextensional actuator using a homodyne interferometer and the J(1)-J(4) method

Ctr Univ Rio Preto; Ctr Univ Catolico; Ctr Univ Lins; Inst Pesquisas Tecnol; Universidade Estadual Paulista (Unesp); Universidade de São Paulo (USP) (Institute of Electrical and Electronics Engineers (IEEE), 2007-06-01)

Piezoelectric transducers are widely used in high-resolution positioning systems. This paper reports the experimental analysis of a novel piezoelectric flextensional actuator (PFA), which is designed by using the ...

Analysis of linearity and frequency response of a novel piezoelectric flextensional actuator using a homodyne interferometer and the J1 - J4 method

Centro Universitário de Rio Preto; Centro Universitário Católico; Centro Universitário de Lins; Instituto de Pesquisas Tecnológicas; Universidade Estadual Paulista (UNESP); Universidade de São Paulo (USP) (2007-06-01)

Bandwidth smearing in infrared long-baseline interferometry. Application to stellar companion search in fringe-scanning mode.

Lachaume, Regis; Berger, Jean-Philippe. (2013)

Michelson interferometer vibrometer using self-correcting synthetic-heterodyne demodulation

University of Limerick; Universidade Estadual Paulista (Unesp) (Optical Soc Amer, 2015-06-20)

Synthetic-heterodyne demodulation is a useful technique for dynamic displacement and velocity detection in interferometric sensors, as it can provide an output signal that is immune to interferometric drift. With the advent ...

VLT/SPHERE- and ALMA-based shape reconstruction of asteroid (3) Juno*

Viikinkoski, M.; Kaasalainen, M.; Durech, J.; Carry, B.; Marsset, M.; Fusco, T.; Dumas, C.; Merline, W.; Yang, B.; Berthier, J.; Kervella, Pierre; Vernazza, P. (EDP Sciences, 2015)

We use the recently released Atacama Large Millimeter Array (ALMA) and VLT/SPHERE science verification data, together with earlier adaptive-optics images, stellar occultation, and lightcurve data to model the 3D shape and ...

Optimization of the two-stage single-pump erbium-doped fiber amplifier with high amplification for low frequency nanoscale pulses

MIGUEL ANGEL BELLO JIMENEZ; EVGENY KUZIN; BALDEMAR IBARRA ESCAMILLA; ARIEL FLORES ROSAS (Society of Photo-Optical Instrumentation EngineersOptical Engineering, 2007)
