Wave-front correction with a multilevel stochastic parallel gradient descent technique

An adaptive optics (AO) system composed of multiple control levels based on the stochastic parallel gradient descent (SPGD) technique is discussed. Results of numerical simulations demonstrate that the convergence rate of 3-level SPGD wave-front correction increased by 23% compared with that of the usual SPGD wave-front correction.
