System overview of the VLTI Spectro-Imager
L. Jocou, J. P. Berger, F. Malbet +30
The VLTI Spectro Imager project aims to perform imaging with a temporal resolution of 1 night and with a maximum angular resolution of 1 milliarcsecond, making best use of the Very…
Fringe tracking and spatial filtering: phase jumps and dropouts
David F. Buscher, John S. Young, Fabien Baron +1
Fringe tracking in interferometers is typically analyzed with the implicit assumption that there is a single phase associated with each telescope in the array. If the telescopes ha…
VSI: the VLTI spectro-imager
F. Malbet, D. Buscher, G. Weigelt +51
The VLTI Spectro Imager (VSI) was proposed as a second-generation instrument of the Very Large Telescope Interferometer providing the ESO community with spectrally-resolved, near-i…
Milli-arcsecond astrophysics with VSI, the VLTI spectro-imager in the ELT era
F. Malbet, D. Buscher, G. Weigelt +49
Nowadays, compact sources like surfaces of nearby stars, circumstellar environments of stars from early stages to the most evolved ones and surroundings of active galactic nuclei c…
VSI: a milli-arcsec spectro-imager for the VLTI
Fabien Malbet, Pierre Kern, Jean-Philippe Berger +14
VLTi Spectro-Imager (VSI) is a proposition for a second generation VLTI instrument which is aimed at providing the ESO community with the capability of performing image synthesis a…
Improvements for group delay fringe tracking
A. G. Basden, D. F. Buscher
Group delay fringe tracking using spectrally-dispersed fringes is suitable for stabilising the optical path difference in ground-based astronomical optical interferometers in low l…
Numerical Simulations of Pinhole and Single Mode Fibre Spatial Filters for Optical Interferometers
J. W. Keen, D. F. Buscher, P. J. Warner
We use a numerical simulation to investigate the effectiveness of pinhole spatial filters at optical/IR interferometers and to compare them with single-mode optical fibre spatial f…
