Paper Abstract

We report on an ongoing experiment at the Starfire Optical Range to study anisoplanatism and investigate a method of mitigating its effect on adaptive optics systems. We have collected Hartmann sensor wave front measurements on binary stars having a variety of separations and have reconstructed wave fronts based on these measurements. At the same time the wave front data was collected, we measured the C2n profile using a balloon-borne instrument. Using these data, we plan to study anisoplanatism in terms of the structure function and Zernike polynomials. We also plan to investigate whether wave front compensation can be improved by moving the wave front corrector from the aperture plane to a plane determined from the refractive index profile.
