1. An adaptive optics control system for compensating distorted wavefronts each having a plurality of states including at least one of a velocity, intensities, phase slopes, and branch points, the system comprising:

  • a wavefront corrector having a surface controlled by a plurality of actuators;

    at least one wavefront sensor adapted to measure at least one state of the wavefront at a current point in time and to generate wavefront sensor output signals indicative of the at least one measured wavefront state; and

    a state space wavefront reconstructor adapted to receive the wavefront sensor output signals and generate a plurality of correction signals based thereon to be applied to the wavefront corrector.
