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…
Recurrence quantification analysis as a post-processing technique in adaptive optics high-contrast imaging
M. Stangalini, G. Li Causi, F. Pedichini +8
In this work we explore the possibility of using Recurrence Quantification Analysis (RQA) in astronomical high-contrast imaging to statistically discriminate the signal of faint ob…
Speckle statistics in adaptive optics images at visible wavelengths
Marco Stangalini, Fernando Pedichini, Enrico Pinna +11
Residual speckles in adaptive optics (AO) images represent a well-known limitation on the achievement of the contrast needed for faint source detection. Speckles in AO imagery can…
A virtual coronagraphic test bench for SHARK-NIR, the second-generation high contrast imager for the Large Binocular Telescope
D. Vassallo, E. Carolo, J. Farinato +21
In this article, we present a simulator conceived for the conceptual study of an AO-fed high-contrast coronagraphic imager. The simulator implements physical optics: a complex dist…
SHARK-NIR, the coronagraphic camera for LBT, moving toward construction
Jacopo Farinato, Francesca Bacciotti, Carlo Baffa +37
SHARK-NIR is one of the two coronagraphic instruments proposed for the Large Binocular Telescope. Together with SHARK-VIS (performing coronagraphic imaging in the visible domain),…
High Contrast Imaging in the Visible: First Experimental Results at the Large Binocular Telescope
F. Pedichini, M. Stangalini, A. Ambrosino +13
In February 2014, the SHARK-VIS (System for High contrast And coronography from R to K at VISual bands) Forerunner, a high contrast experimental imager operating at visible wavelen…
Multiple field-of-view MCAO for a Large Solar Telescope: LOST simulations
Marco Stangalini, Francesco Berrilli, Dario Del Moro +1
In the framework of a 4m class Solar Telescope we studied the performance of the MCAO using the LOST simulation package. In particular, in this work we focus on two different metho…
MCAO for the European Solar Telescope: first results
M. Stangalini, R. Piazzesi, D. Del Moro +1
We analise the efficiency of wavefront reconstruction in the MultiConjugate Adaptive Optics system for the European Solar Telescope (EST). We present preliminary results derived fr…
