Single star scidar: atmospheric parameters profiling using the simulated annealing algorithm

Abstract

In this paper, we present a new method to estimate, for each turbulent layer labelled i, the horizontal wind speed v(hi), the standard deviation of the horizontal wind speed fluctuations σv(hi) and the integrated value of C2n over the thickness Δhi of the turbulent layer C2n(hi)Δhi, where hi is the altitude of the turbulent layer. These parameters are extracted from single star scintillation spatiotemporal cross-correlation functions of atmospheric speckles obtained within the generalized mode. This method is based on the simulated annealing algorithm to find the optimal solution required to solve the problem. Astrophysics parameters for adaptive optics are also calculated using C2n(hi) and v (hi) values. The results of other techniques support this new method.
