Wide-Field Adaptive Optics systems will be a key component of the future generation of Extremely Large Telescopes. All the components of such Adaptive Optics systems have to be precisely specified using the atmospheric turbulence parameters of the si

The future generation of extremely large telescopes will be certainly equipped with wide-field adaptive optics systems. All the components of such adaptive optics systems have to be precisely specified, and most of the technical specifications are re

The basic problem of LINC-NIRVANA (LN) imaging is to combine the different images for getting a single image, possibly with a resolution close to that of a 22.8 m mirror in all directions. This result can be hardly reached in practice because it depe

The effect of atmospheric turbulence on the imaging of scenes, for horizontal propagation of the light over a distance of 20 km, 15 m above the sea surface, was analysed at visible wavelengths using a 20 cm telescope. Point-source images were recorde

We describe an analytical method to recover the high light level probability density function (PDF) P( Omega ) of a random field from the knowledge of its PDF p(n) in photon-counting mode. The inversion of the Poisson transform that relates the two P

This paper describes a method of beam-combination in the so-called hypertelescope imaging technique recently introduced by Labeyrie in optical interferometry. The method we propose is an alternative to the Michelson pupil reconfiguration that suffers

LINC/NIRVANA (LN) is the German-Italian beam combiner for the Large Binocular Telescope (LBT). It is a Fizeau interferometer and it will provide multiple images of the same target corresponding to different orientations of the baseline. For each one

In this paper, we propose a general method to devise maximum likelihood penalized (regularized) algorithms with positivity constraints. Moreover, we explain how to obtain 'product forms' of these algorithms. The algorithmic method is based on Kuhn?Tu

We propose regularized versions of Maximum Likelihood algorithms for Poisson process with non-negativity constraint. For such process, the best-known (non- regularized) algorithm is that of Richardson-Lucy, extensively used for astronomical applicati
