ABSTRACT
A new class of optimal wave-front estimators for adaptive-optics systems that minimize time-delay errors that are due to atmospheric winds is developed. These matrices utilize the past time history of the servo system by means of temporal Kolmogorov cross-covariance matrices. Except in the simplest case, a nonlinear matrix equation must be iteratively solved. Strehl ratio performance for selected estimators is given.
