Issue Date: | 2016 | Volume: | Adaptive Optics Systems V | Editors: | Marchetti, Enrico; Close, Laird M.; Véran, Jean-Pierre | Series: | PROCEEDINGS OF SPIE | Number: | 9909 | First Page: | 99090U | Abstract: | The SPHERE (Spectro-Polarimetric High-contrast Exoplanet Research) instrument aims at detecting extremely faint sources (giant extrasolar planets) in the vicinity of bright stars<SUP>1</SUP>. Such a challenging goal requires the use of a very-high-order performance Adaptive Optics [AO] system feeding the scientific instruments with a quasi-perfect flat wave front corrected from all the atmospheric turbulence and internal defects. This AO system, called SAXO (Sphere Ao for eXoplanet Observation) is the heart of the instrument, a heart beating 1200 time per second and providing unprecedented image quality for a large ground based telescope at optical/near infrared wavelength. We will present the latest results obtained on-sky, demonstrating its exceptional performance (in terms of correction quality, stability and robustness) and tremendous potentiality for high contrast imaging and more specifically for exoplanet discovery. | Conference Name: | Adaptive Optics Systems V | Conference Place: | Edinburgh, UK | Conference Date: | 26 June-1 July, 2016 | URI: | http://hdl.handle.net/20.500.12386/24583 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9909/1/SAXO-the-SPHERE-extreme-AO-system--on-sky-final/10.1117/12.2233319.short | ISSN: | 0277-786X | ISBN: | 9781510601970 9781510601987 |
