TIPTOP: a new tool to efficiently predict your favorite AO PSF
Benoit Neichel, Olivier Beltramo-Martin, Cedric Plantet +7
The Adaptive Optics (AO) performance significantly depends on the available Natural Guide Stars (NGSs) and a wide range of atmospheric conditions (seeing, Cn2, windspeed,...). In o…
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…
Prospects of Deep Field Surveys with Global-MCAO on an ELT
Elisa Portaluri, Valentina Viotto, Roberto Ragazzoni +12
Several astronomical surveys aimed at the investigation of the extragalactic components were carried out in order to map systematically the universe and its constituents. An excell…
Data processing on simulated data for SHARK-NIR
E. Carolo, D. Vassallo, J. Farinato +22
A robust post processing technique is mandatory to analyse the coronagraphic high contrast imaging data. Angular Differential Imaging (ADI) and Principal Component Analysis (PCA) a…
A Holographic Diffuser Generalised Optical Differentiation Wavefront Sensor
Luca Marafatto, Roberto Ragazzoni, Daniele Vassallo +12
The wavefront sensors used today at the biggest World's telescopes have either a high dynamic range or a high sensitivity, and they are subject to a linear trade off between these…
A testing facility for AO on-sky demonstrations at the Copernico's Telescope within the ADONI framework
S. Chinellato, R. Ragazzoni, J. Farinato +21
In the context of ADONI - the ADaptive Optics National laboratory of INAF - we are arranging for a facility, accessible to the AO community, in which visiting multi-purpose instrum…
