Dispersed fringe tracking with the multi-r(0) apertures of the Grand Interféromètre à 2 Télescopes.
Laurent Koechlin,Peter R. Lawson,Denis Mourard,A. Blazit,D. Bonneau,Frédéric Morand,Ph. Stee,Isabelle Tallon-Bosc,Farrokh Vakili +8 more
TL;DR: A new fringe tracker based on photon-counting detectors and real-time image processing has been implemented on the Grand Interféromètre à 2 Télescopes at the Observatoire de la Cote d'Azur.
Journal ArticleDOI
Speckle observations with PISCO in Merate – I. Astrometric measurements of visual binaries in 2004
Marco Scardia,Jean-Louis Prieur,M. Sala,Mauro Ghigo,Laurent Koechlin,Eric Aristidi,F. Mazzoleni +6 more
TL;DR: In this paper, relative astrometric measurements of visual binaries taken during the second semester of 2004 with the Pupil Interferometry Speckle camera and Coronagraph (PISCO) at the 1-m Zeiss telescope of the Brera Astronomical Observatory, in Merate, Italy.
Journal ArticleDOI
The 'Pisco' Speckle Camera at Pic Du Midi Observatory
TL;DR: PISCO as discussed by the authors is a speckle camera designed and built at Observatoire Midi-Pyrenees, which can be set in various operating modes: full pupil imaging, masked-pupil imaging, spectroscopy, wavefront sensor and stellar coronagraphy.
Proceedings ArticleDOI
Hypertelescope imaging: from exo-planets to neutron stars
Antoine Labeyrie,Hervé Le Coroller,Julien Dejonghe,Frantz Martinache,V. Borkowski,O. Lardière,Laurent Koechlin +6 more
TL;DR: In this paper, a precursor array of flying mirrors driven by solar sails in geostationary orbit is presented, which can in principle resolve the green spots on an Earth seen at several parsecs.
Journal ArticleDOI
Speckle Observations of Double Stars with PISCO at Pic du Midi: Measurements in 1998
TL;DR: In this paper, the PISCO speckle camera at Pic du Midi was used to detect double binary stars with angular separation in the range 1-10, which were mainly selected among grade 3 orbits to improve the accuracy of their orbits and constrain their masses.
