based on the simulated annealing principle. This method allows us to retrieve, for each turbulent layer, the altitude, the integrated value of the refractive-index structure coefficient over the thickness of the turbulent layer, the horizontal wind speed and the standard deviation of
the horizontal wind speed fluctuations. These atmospheric parameters are extracted from the spatio-temporal cross-correlation of a single star scintillation (Single Star SCIDAR). The temporal
sampling, which depends on the camera and computer features, is one profile every 11.2 seconds. Thus, it is possible to get the seeing and other parameters for adaptive optics with the same
temporal sampling. This technique has allowed us to bring to reality the mobile SCIDAR system using a small telescope diameter which is a useful means for site testing.
