Self-calibration of adaptive optics systems. Application to the THEMIS solar telescope
Clementine Bechet, Eric Thiebaut, Michel Tallon +3
The interaction matrix models the effects of deformable mirror (DM) commands as perceived by the wavefront sensor (WFS) and is the cornerstone of the Adaptive Optics (AO) control.…
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…
