SAXO+, the second-stage adaptive optics for SPHERE: NCPA compensation and dark-hole loop with a pyramid wavefront sensor
Johan Mazoyer, Charles Goulas, Raphaël Galicher +21
The SAXO+ upgrade of the VLT/SPHERE adaptive optics system introduces a second-stage near-infrared pyramid wavefront sensor to improve high-contrast imaging, making accurate calibr…
Upgrading SPHERE with the second stage AO system SAXO+: non-common path aberrations estimation and correction
Johan Mazoyer, Charles Goulas, Fabrice Vidal +16
SAXO+ is a planned enhancement of the existing SAXO, the VLT/ SPHERE adaptive optics system, deployed on ESO's Very Large Telescope. This upgrade is designed to significantly enhan…
Numerical simulations for the SAXO+ upgrade: Performance analysis of the adaptive optics system
Charles Goulas, Raphaël Galicher, Fabrice Vidal +16
SPHERE, operating at the VLT since 2014, is currently one of the high-contrast instruments with a higher performance. Its adaptive optics system, known as SAXO, will be upgraded to…
SAXO+ upgrade : second stage AO system end-to-end numerical simulations
Charles Goulas, Fabrice Vidal, Raphaël Galicher +14
SAXO+ is a proposed upgrade to SAXO, the AO system of the SPHERE instrument on the ESO Very Large Telescope. It will improve the capabilities of the instrument for the detection an…
Upgrading the high contrast imaging facility SPHERE: science drivers and instrument choices
A. Boccaletti, G. Chauvin, F. Wildi +71
SPHERE+ is a proposed upgrade of the SPHERE instrument at the VLT, which is intended to boost the current performances of detection and characterization for exoplanets and disks. S…
IRDIS, the dual-band imager camera of SPHERE: testing the performances in laboratory
A. Zurlo, A. Vigan, C. Moutou +12
Next year the second generation instrument SPHERE will begin science operations at the Very Large Telecope (ESO). This instrument will be dedicated to the search for exoplanets thr…
