Popis: The futures large telescopes will be certainly equipped with Multi-Conjugate Adaptive Optics systems. The optimization of the performances of these techniques requires a precise specification of the different components of these systems. Major of these technical specifications are related to the atmospheric turbulence particularly the structure constante of the refractive index C 2 n ( h ) and the outer scale L 0 ( h ). New techniques based on the moon limb observation for the monitoring of the C 2 n ( h ) and L 0 ( h ) profiles with high vertical resolution will be presented.
