Wavefront correction by use of Zernike polynomials and ALOPEX stochastic optimizationWavefront correction by use of Zernike polynomials and ALOPEX stochastic optimization Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-161999enSome first results of simulation studies for the control of deformable mirrors used to correct the effects of atmospheric turbulence to the image quality in a 1.5m telescope at a wavelength of 0.5μn are reported here. Images based on Kolmogorov turbulence have been formed and an attempt has been made to correct them via a deformable mirror, incident to the telescope wavefront, using the stochastic optimization ALOPEX parallel algorithm. The deformable mirror surface is parameterized with Zernike polynomials. The objective is to obtain good quality images as quickly as possible. It is found that images with a Strehl ratio of greater than 0.8 can be obtained by controlling the tip-tilt and spherical corrections (five parameters). Initial results are presented in regard to the speed of convergence of the optimization algorithm.http://creativecommons.org/licenses/by/4.0/Journal of Applied Science and Computation35252-274 Zakynthinaki Maria Ζακυνθινακη Μαρια Saridakis Ioannis Σαριδακης Ιωαννης Kalogeropoulos, Theo Greek mathematics mathematics greek greek mathematics
