AbstractMZA proposes development and evaluation of optimal estimation methods for beacon measurement supporting adaptive optics compensation of aero-optics and free-stream turbulence. The proposed method takes into account the modal covariance properties of near-field and far-field beacon sources and their relation to the phase required for HEL correction. Optimal estimation can be adapted to several available options for beacon placement. The proposed methods will be validated through wave-optics simulation using aero-optics and free-stream turbulence with the appropriate beacon sources. To quantify the underlying statistics of the aero-optical disturbances for which there is no theoretical construct, we propose laboratory wavefront sensor measurements of aero-optical flow capitalizing on the expertise of our partner, Notre Dame. We will also perform laboratory characterizations of air-breakdown "laser sparks" from a short-wavelength laser. These measurements will demonstrate the feasibility of forming such a beacon in a follow-on phase of the program and will provide design information to assess our hardware concept. We will develop a preliminary design for a meaningful Phase II laboratory demonstration of the concept advanced in Phase I. This plan will address implementation issues related to beacon formation and beacon measurement supporting application of the optimal estimation methods.
