Abstract

The Adaptive Optics Facility (AOF) is a project that aims to transform the VLT UT4 into an adaptive telescope and therefore to provide all its science instruments with turbulence corrected wavefronts. When used in its wide-field modes, the AOF will allow to get a real time estimate of the turbulence distribution in the atmosphere, allowing an optimization of the system correction. The so-called Wind Profiler (or Fourier Deconvolution) algorithm has been adapted to the AOF configuration and validated through extensive tests. We show how it behaves under different modes and under typical Paranal seeing conditions.
