INGOT WFS for LGSs: First Results from Simulations
Elisa Portaluri, Valentina Viotto, Roberto Ragazzoni +10
The Ingot WFS, a Pyramid-like WFS, has been proposed as a relief to the LGS spot elongation. Actually, the artificial sources are confined in an excited cigar-shaped region in the…
Deep observations with an ELT in the Global Multi Conjugated Adaptive Optics perspective
Elisa Portaluri, Valentina Viotto, Roberto Ragazzoni +6
Deep observations of the Universe, usually as a part of sky surveys, are one of the symbols of the modern astronomy because they can allow big collaborations, exploiting multiple f…
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,…
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…
MICADO PSF-Reconstruction work package description
Matteo Simioni, Carmelo Arcidiacono, Andrea Grazian +25
The point spread function reconstruction (PSF-R) capability is a deliverable of the MICADO@ESO-ELT project. The PSF-R team works on the implementation of the instrument software de…
XAO-assisted coronagraphy with SHARK NIR: from simulations to laboratory tests
Gabriele Umbriaco, Elena Carolo, Daniele Vassallo +22
Several Extreme Adaptive Optics (XAO) systems dedicated to the detection and characterisation of the exoplanets are currently in operation for 8-10 meter class telescopes. Coronagr…
