First laboratory demonstration of iEFC for high-contrast imaging at small angular separation on ELT scales
Charles Sallard, Patrice Martinez, Alain Spang +7
Implicit electric field conjugation (iEFC) is an efficient, model-free wavefront control technique for dark hole creation. Its model-free nature, relying on calibration with real d…
First Light for the GRAVITY+ Adaptive Optics: Extreme Adaptive Optics for the Very Large Telescope Interferometer
GRAVITY+ Collaboration, :, F. Allouche +137
GRAVITY+ improves by orders of magnitude the sensitivity, sky-coverage and contrast of the Very Large Telescope Interferometer (VLTI). A central part of this project is the develop…
ANDES, the high resolution spectrograph for the ELT: science goals, project overview and future developments
A. Marconi, M. Abreu, V. Adibekyan +286
The first generation of ELT instruments includes an optical-infrared high-resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion E…
The GRAVITY+ Project: Towards All-sky, Faint-Science, High-Contrast Near-Infrared Interferometry at the VLTI
GRAVITY+ Collaboration, :, Roberto Abuter +134
The GRAVITY instrument has been revolutionary for near-infrared interferometry by pushing sensitivity and precision to previously unknown limits. With the upgrade of GRAVITY and th…
Impact of local turbulence on high-order adaptive optics
Hugo Nowacki, Jean-Baptiste Le Bouquin, Carole Gouvret +9
We present an experiment set to address a standard specification aiming at avoiding local turbulence inside the Coudé train of telescopes. Namely, every optical surface should be k…
Building a GRAVITY+ Adaptive Optics Test Bench
The Gravity Plus Consortium, Florentin Millour, Philippe Berio +22
We present the testbench aimed at integrating the GRAVITY+ adaptive optics GPAO. It consists of two independent elements, one reproducing the Coud{é} focus of the telescope, includ…
