The crossed-sine wavefront sensor: first tests and results
Laura Schreiber, Yan Feng, Alain Spang +4
The crossed-sine wavefront sensor (WFS) is a pupil plane wavefront sensor that measures the first derivatives of the wavefront. It is made by three main components: a gradient tran…
Ariel: Enabling planetary science across light-years
Giovanna Tinetti, Paul Eccleston, Carole Haswell +313
Ariel, the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, was adopted as the fourth medium-class mission in ESA's Cosmic Vision programme to be launched in 2029. Durin…
Prototype of a laser guide star wavefront sensor for the Extremely Large Telescope
M. Patti, M. Lombini, L. Schreiber +5
The new class of large telescopes, as the future ELT, are designed to work with Laser Guide Star (LGS) tuned to a resonance of atmosphere sodium atoms. This wavefront sensing techn…
Stellar photometry with Multi Conjugate Adaptive Optics
Giuliana Fiorentino, Davide Massari, Alan McConnachie +14
We overview the current status of photometric analyses of images collected with Multi Conjugate Adaptive Optics (MCAO) at 8-10m class telescopes that operated, or are operating, on…
The numerical simulation tool for the MAORY multiconjugate adaptive optics system
Carmelo Arcidiacono, Laura Schreiber, Giovanni Bregoli +14
The Multiconjugate Adaptive Optics RelaY (MAORY) is and Adaptive Optics module to be mounted on the ESO European-Extremely Large Telescope (E-ELT). It is a hybrid Natural and Laser…
High-precision astrometry towards ELTs
Davide Massari, Giuliana Fiorentino, Eline Tolstoy +13
With the aim of paving the road for future accurate astrometry with MICADO at the European-ELT, we performed an astrometric study using two different but complementary approaches t…
A method for space-variant deblurring with application to adaptive optics imaging in astronomy
Andrea La Camera, Laura Schreiber, Emiliano Diolaiti +4
Images from adaptive optics systems are generally affected by significant distortions of the point spread function (PSF) across the field of view, depending on the position of natu…
Impact of Sodium Layer variations on the performance of the E-ELT MCAO module
L. Schreiber, E. Diolaiti, C. Arcidiacono +4
Multi-Conjugate Adaptive Optics systems based on sodium Laser Guide Stars may exploit Natural Guide Stars to solve intrinsic limitations of artificial beacons (tip-tilt indetermina…
End to end numerical simulations of the MAORY multiconjugate adaptive optics system
Carmelo Arcidiacono, Laura Schreiber, Giovanni Bregoli +6
MAORY is the adaptive optics module of the E-ELT that will feed the MICADO imaging camera through a gravity invariant exit port. MAORY has been foreseen to implement MCAO correctio…
Studying the metallicity gradient in Virgo Ellipticals with E-ELT photometry of resolved stars
Laura Schreiber, Laura Greggio, Renato Falomo +2
The next generation of large aperture ground based telescopes will offer the opportunity to perform accurate stellar photometry in very crowded fields. This future capability will…
Layer Oriented Wavefront sensor for MAD on Sky operations
Carmelo Arcidiacono, Matteo Lombini, Roberto Ragazzoni +15
The Multiconjugate Adaptive optics Demonstrator (MAD) has successfully demonstrated on sky both Star Oriented (SO) and Layer Oriented (LO) multiconjugate adaptive optics techniques…
Laser Guide Stars for Extremely Large Telescopes: Efficient Shack-Hartmann Wavefront Sensor Design using Weighted center-of-gravity algorithm
L. Schreiber, I. Foppiani, C. Robert +3
Over the last few years increasing consideration has been given to the study of Laser Guide Stars (LGS) for the measurement of the disturbance introduced by the atmosphere in optic…
