Characteristics Optical Turbulence by Digital Modeling CAOS

Optical turbulence have been estimated by study the error balance in the adaptive optics system in global error (2 post. OA). Using the simulation of CAOS system, and compare with Noll errors (residual error). Where I had evaluated the 2 photon as a function of N photon, also evaluated the Strehl (S) as a function of magnitude (h), as a result measure of the coronagraphs performance, extinction and contracture improve I comp. /I star.
