“…These AO systems are currently tested and implemented on the present generation facilities and they are planned to be implemented on the ELTs in the next decades. For example at the E-ELT the near-infrared spectrograph HARMONI (Thatte et al 2016) will work with a LTAO system, MAORY (Diolaiti et al 2016) is a MCAO system that will feed the imager MICADO (Davies et al 2016) and the multi-object spectrograph MOSAIC (Hammer et al 2016) will be feed by a MOAO system. The wider is the field of view, the higher is the resolution with which one has to know the vertical stratification of the turbulence in advance.…”

One of the main goals of the feasibility study MOSE (MOdelling ESO Sites) is to evaluate the performances of a method conceived to forecast the optical turbulence above the ESO sites of the Very Large Telescope and the European-Extremely Large Telescope in Chile. The method implied the use of a dedicated code conceived for the optical turbulence (OT) called Astro-Meso-Nh. In this paper we present results we obtained at conclusion of this project concerning the performances of this method in forecasting the most relevant parameters related to the optical turbulence (C 2 N , seeing ε, isoplanatic angle θ 0 and wavefront coherence time τ 0 ). Numerical predictions related to a very rich statistical sample of nights uniformly distributed along a solar year and belonging to different years have been compared to observations and different statistical operators have been analyzed such as the classical bias, RMSE, σ and more sophisticated statistical operators derived by the contingency tables that are able to quantify the score of success of a predictive method such as the percentage of correct detection (PC) and the probability to detect a parameter within a specific range of values (POD). The main conclusions of the study tell us that the Astro-Meso-Nh model provides performances that are already very good to definitely guarantee a not negligible positive impact on the Service Mode of top-class telescopes and ELTs. A demonstrator for an automatic and operational version of the Astro-Meso-Nh model will be soon implemented on the sites of VLT and E-ELT.

Adaptive Optics (AO) has become a key technology for the largest ground-based telescopes currently under, or close to beginning of, construction. AO is an indispensable component and has basically only one task, that is to operate the telescope at its maximum angular resolution, without optical degradations resulting from atmospheric seeing. Based on three decades of experience using AO usually as an add-on component, all extremely large telescopes and their instrumentation are designed for di®raction limited observations from the very beginning. This paper illuminates various approaches of the ELT, the Giant Magellan Telescope (GMT), and the Thirty-Meter Telescope (TMT), to fully integrate AO in their designs. The paper concludes with a brief look into the requirements that high-contrast imaging poses on AO.

“…Although its feasibility had been earlier tested on-sky, 3,4 the actual implementation of MCAO for nighttime astronomy had to wait until 2007, when the multiconjugate adaptive optics demonstrator (MAD) exhibited various MCAO schemes on the very large telescope. 5,6 Despite a proposed upgrade 7 and plans for future implementations, [8][9][10][11] the only currently working nighttime MCAO systems in the world are GeMS at the Gemini South telescope 12,13 and LINC-NIRVANA (LN) at the Large Binocular Telescope (LBT). [14][15][16][17] MCAO systems promise to provide a uniform point spread function (PSF) across a wide field-of-view (FoV), using multiple guide stars, either laser-guide stars (LGSs) or natural-guide stars (NGSs).…”

Multiconjugate adaptive optics (MCAO) promises uniform wide-field atmospheric correction. However, partial illumination of the layers at which the deformable mirrors are conjugated results in incomplete information about the full turbulence field. We report on a working solution to this difficulty for layer-oriented MCAO, including laboratory and on-sky demonstration with the LINC-NIRVANA instrument at the Large Binocular Telescope. This approach has proven to be simple and stable.
