In Adaptive optics (AO) systems, the most important stage of reconstruction process is wavefront reconstruction based on wavefront slopes. Speed and accuracy of this stage determine AO efficiency. Because of computational burden in the traditional method of wavefront reconstruction, when the numbers of mirror’s actuators are increase, reconstruction process will have some errors. An alternative method for wavefront reconstruction is iterative Fourier transforms (IFT). In this article three different equations were investigated in IFT algorithms to reconstruct propagated Gaussian beam in turbulent atmosphere. Simulations show that the reconstructed wavefront based on Fried geometry has bigger Strehl ratio.
Keywords: Adaptive Optics, Iterative Fourier Transforms algorithm, wavefront reconstruction, Strehl ratio, fried geometry
