The minimum-variance (MV) phase residual Linear-Quadratic-Gaussian (LQG) solution in Adaptive Optics (AO) using fast iterative methods is outlined. Standard LQG computational burden scaling as O(n2) is shown to be O(n log n) using spectral methods. Proof-of-concept is made through Monte Carlo simulations.
