A la hora de planificar un proyecto la gestión de las dependencias técnicas entre tareas ya supone un desafío.  Añadamos a la coctelera las dependencias circunstanciales y, por qué no, sumerjamos el experimento en una organización matricial donde todos los miembros del equipo trabajan en varios proyectos.

Prof. Caroline Kulcsár
Université Paris-Saclay


In this talk, I will start by briefly presenting the Institut d'Optique Graduate School and the Laboratoire Charles Fabry, where I conduct my research. Then I will explain the principle of adaptive optics and discuss some issues related to the control of AO systems. This will lead to the general ideas behind high-performance control. In particular, I will explain why high-performance control can outperform the standard integrator. Some results of on-sky experiments will be shown, and I will conclude the talk by presenting our PhD students working through research collaborations.

Al objeto de incrementar la cobertura de cielo proporcionada por el sistema de óptica adaptativa de GTC, durante los últimos 4 años se ha estado trabajando en la incorporación de un sistema de estrella guía láser de Sodio. A través de esta charla se repasará el estado actual del proyecto enfatizando aquellos aspectos relacionados con el sistema óptico de lanzamiento de la estrella guía.

An original method for measuring the atmospheric turbulence is described, capable of even measuring the tip-tilt, which normally requires a dedicated natural star and nowadays defines the practical limit of the adaptive optics technique. The method is based in the illumination of a wide area of the Sodium Layer, and to use their inhomogeneities as a reference. Sevaral analysis and simulation results will be presented.

Thanks to its unique capabilities, the MUSE integral field spectrograph at ESO VLT has given us new insight of the Universe at high redshift. In this talk I will review some breakthrough in the observation of the Hubble Ultra Deep field with MUSE including the discovery of a new population of faint galaxies without HST counterpart in the UDF and the ubiquitous presence of extended Lyman-alpha haloes around galaxies.

I will summarize the two well proved techniques for high spatial resolution: Lucky Imaging and Adaptive Optics and the work of our group in this field. I will also introduce the state-of-the-art new instrument Adaptive Optics Lucky Imager (AOLI). On AOLI, both techniques merge providing a very versatile answer on the visible range. Some first science on the T-Tauri system LkHa 262/263 in the MBM 12 cloud will be reported together with a review of the next steps to be developed.

Job Manager for the LGS Systems Research and Development at ESO


In collaboration with member states institutes, the use of the synergies with ESO is producing first important results in the R&D for Laser Guide Star adaptive optics, to be used for the large and extremely large telescope projects.

In this talk we will report on the preliminary results of the current campaign on LGS return flux with laser guide stars at Observatorio de el Teide and the foreseen tests of the EELT LGS-AO scheme, to be done at the WHT starting in summer 2016. An outlook will be given on the proposal for further feasibility tests at WHT in 2018-19, to experiment novel LGS-AO schemes using uplink beam correction and pyramid wavefront sensing. The demonstration is for a LGS-AO scheme giving high Strehl on the EELT and adaptive optics in the visible on 8m class telescopes.

In the past years, intensive Site Characterization campaigns have been performed to chose the sites for the future giant ELTs. Various atmospheric turbulence profilers with different resolution and sensed altitude ranges have been used, as well as climatological tools and satellite data analysis. Mixing long term statistics at low altitude resolution with high resolution data collected during short term campaigns allows to produce the reference profiles as input to the Adaptive Optics (AO) instrument performance estimators. In this talk I will perform a brief review of the principal and most used instruments and tools in order to give to the audience a panorama of the work and the efforts to monitor the atmospheric turbulence for astronomical purposes.

Adaptive optics systems rely on a real-time control system which is responsible for receiving wavefront sensor information and computing and applying the necessary correction to the deformable mirrors. Historically, real-time control systems have relied on customised hardware comprised of multiple FPGA and DSP systems, which high complexity. More recently it has been demonstrated that conventional PCs are now sufficiently powerful to to perform this task. In this talk, I will present an open-source real-time control system, DARC, discuss its implementation on the CANARY AO system at the William Herschel Telescope, and cover the algorithms available. Extension to ELT-scale operation will be discussed, including hardware and detector considerations. The internal architecture of this modular system will be presented, with a case being made for its suitability for implementation on any AO system type, on any telescope.
