Rationale

In the wake of next generation astronomical instruments and telescopes, high-angular resolution observations with complex optical systems hinge on accurate knowledge of turbulence phenomena, be it in the free atmosphere, at the ground or within the dome.
Therefore, turbulence profiling is key to the successful design, deployment and exploitation of state-of-the-art instruments. The spatio-temporal nature of turbulence is particularly important to runtime optimisation of tomographic systems and generally in understanding error budgets or post-processing (e.g. PSF reconstruction).

This 2-day meeting focuses on recent progress on turbulence characterisation, be it for night-time or day-time astronomy, using dedicated hardware for concomitant profiling with observations or not. Novel techniques and results on site characterisation, the production of representative profiles and the forecast ahead of observations are to be covered.

Authors covering the the following (non-exhaustive) list of topics are encouraged to submit an abstract for a presentation (oral). Posters may also be accepted.
• Site Testing And Characterisation Campaigns
• New optical/numerical techniques
• Vertical/horizontal profilometry under weak/strong turbulence
• Day-time and night-time (wide-field) applications
• Spatio-temporal behaviour of turbulence, variability, wind-profiles
• Vertical stratification (dome, ground, free atmosphere)
• Impact of parameters accurate knowledge on high-angular resolution instruments performance, both on-line and off-line (error budgets, post-processing)
• Use of natural and laser guide stars on large-scale systems
• Impact of mis-reg parameters / joint estimation and opto-mechanical parameters

Abstract Submission

The submission and registration procedure is the following :

Send a email to profiling_workshop_soc@lam.fr in which you will indicate if you want to
1) register only
2) submit an oral presentation

in the last case please add
1) the title of the communication
2) a short abstract (500 words max)

The deadline for both submissions and registrations is the 3rd of March

Please note that the number of place will be limited to 25 max (room capacity).
Thank to the support of our partners and sponsors, there will be no fees for this workshop.
