Classical adaptive optics is limited by anisoplanatism. New concepts, known as Wide Field Adaptive Optics systems, have been developed in order to go beyond this limitation. These systems analyse atmospheric turbulence within a volume, increasing the correction field. These techniques require a precise knowledge of the Cn2 profile. The purpose...

COupled SLope and scIntillation Detection And Ranging (CO-SLIDAR) is a recent profiling method of the vertical distribution of atmospheric turbulence strength ( Cn2 profile). It takes advantage of correlations of slopes and of scintillation, both measured with a Shack-Hartmann wavefront sensor on a binary star. In this paper, we present the...
