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…
Non-common path aberration compensation and a dark hole loop with a pyramid adaptive optics system: Application to SAXO+
C. Goulas, R. Galicher, F. Vidal +16
In ground-based high-contrast instruments, non-common path aberrations (NCPAs) limit detection performance, as they are unseen by the adaptive optics (AO) wavefront sensor but impa…
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…
