Application de la technique du SCIDAR généralisé aux étoiles simples

In this Note we expose a new technique of characterization of atmospheric turbulence by single-star scintillation analysis. This technique is based on the study of the spatiotemporal cross-correlation function in a conjugated plane in the atmosphere. It permits the retrieval of the horizontal wind velocity, the standard deviation of the wind speed fluctuations, the altitude of each turbulent layer and the integral of the refractive-index structure constant C n 2 ( h ) Δ h over the layer thickness. Our results are in good agreements with other techniques. To cite this article: A. Habib et al., C. R. Physique 6 (2005).
