Pupil plane wavefront sensing for extended and 3D sources
Roberto Ragazzoni, Valentina Viotto, Elisa Portaluri +11
The basic outline of a pupil plane WaveFront Sensor is reviewed taking into account that the source to be sensed could be different from an unresolved source, i.e. it is extended,…
New developments on the Ingot WFS laboratory testing
Tânia Gomes Machado, Simone Di Filippo, Kalyan K. R. Santhakumari +16
The Ingot WFS was designed to overcome some of the challenges present in classical wavefront sensors when they deal with sodium LGSs. This innovative sensor works by sensing the fu…
Multiple spatial frequencies wavefront sensing
Roberto Ragazzoni, Daniele Vassallo, Marco Dima +10
We describe the concept of splitting spatial frequency perturbations into some kind of pupil planes wavefront sensors. Further to the existing approach of dropping higher spatial f…
The Chandra Deep Field South as a test case for Global Multi Conjugate Adaptive Optics
Elisa Portaluri, Valentina Viotto, Roberto Ragazzoni +7
The era of the next generation of giant telescopes requires not only the advent of new technologies but also the development of novel methods, in order to exploit fully the extraor…
INGOT Wavefront Sensor: Simulation of Pupil Images
Valentina Viotto, Elisa Portaluri, Carmelo Arcidiacono +9
The ingot wavefront sensor (I-WFS) has been proposed, for ELT-like apertures, as a possible pupil plane WFS, to cope with the geometrical characteristics of a laser guide star (LGS…
The PLATO Mission
Heike Rauer, Conny Aerts, Juan Cabrera +842
PLATO (PLAnetary Transits and Oscillations of stars) is ESA's M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large numb…
