Abstract
The performance of adaptive optics systems can often be limited by the time lag required between sensing a phase aberration in the wavefront and correcting it. Predictive controllers that can estimate the evolution of the aberrations during this time lag can help to improve the AO system. We seek to enable additional capabilities for future data-driven prediction algorithms by implementing a cross-correlation analysis to identify additional dynamic sources of wavefront perturbation which can then used as inputs for a prediction algorithm.
