Abstract

In this paper we present a Fourier-domain preconditioned conjugate gradient algorithm for the fitting step in Multi-Conjugate Adaptive Optics (MCAO) for extremely large telescopes. This algorithm is fast and robust, and it is convenient to implement with parallel processing in a real-time system. Simulation results are presented for an MCAO system for a 30-meter telescope with 2 deformable mirrors.
