RISTRETTO: Seven Spaxels Single Mode Spectrograph Design
Bruno Chazelas, Christophe Lovis, Nicolas Blind +6
The RISTRETTO project is aiming to build an instrument that will detect the reflected light from close-by exoplanet. It is a two stage instrument: An extreme AO system in the visib…
The GRAVITY metrology system: narrow-angle astrometry via phase-shifting interferometry
M. Lippa, N. Blind, S. Gillessen +26
The VLTI instrument GRAVITY will provide very powerful astrometry by combining the light from four telescopes for two objects simultaneously. It will measure the angular separation…
The fiber coupler and beam stabilization system of the GRAVITY interferometer
O. Pfuhl, M. Haug, F. Eisenhauer +20
We present the installed and fully operational beam stabilization and fiber injection subsystem feeding the 2nd generation VLTI instrument GRAVITY. The interferometer GRAVITY requi…
Astrophotonic micro-spectrographs in the era of ELTs
N. Blind, E. Le Coarer, P. Kern +1
The next generation of Extremely Large Telescopes (ELT), with diameters up to 39 meters, will start opera- tion in the next decade and promises new challenges in the development of…
GRAVITY: the Calibration Unit
N. Blind, F. Eisenhauer, M. Haug +19
We present in this paper the design and characterisation of a new sub-system of the VLTI 2nd generation instrument GRAVITY: the Calibration Unit. The Calibration Unit provides all…
The Planar Optics Phase Sensor: a study for the VLTI 2nd Generation Fringe Tracker
Nicolas Blind, Jean-Baptiste LeBouquin, Olivier Absil +16
In a few years, the second generation instruments of the Very Large Telescope Interferometer (VLTI) will routinely provide observations with 4 to 6 telescopes simultaneously. To re…
