PAPYRUS: one year of on-sky operations
Résumé
The PAPYRUS adaptive optics (AO) bench has been developed to test and maturate new concepts of wavefront
sensors (WFS), control strategies and dedicated hardware such as cameras and deformable mirrors. The bench
will serve as a pathfinder to the challenging AO systems for the upcoming Extremely Large Telescopes (ELTs).
Moreover the bench has already been used as a pedagogical tool to teach adaptive optics to PhD and master
students.
PAPYRUS is made of a modulated pyramid WFS working in the visible band, an EMCCD wavefront sensing
camera and a 17 × 17 deformable mirror. The bench is installed on the T152 (1.52 m diameter) telescope at
Observatoire de Haute Provence (OHP, France) since June 2022. Here we summarise the performance of the
bench and the lessons learnt after one year of on-sky operations with the pyramid WFS
