Abstract

A ground-based stellar interferometer appears to be a potentially useful research tool in studying stellar astrophysics and synthesizing a high resolution stellar image; however, its short-exposure performance is easily degraded by atmospheric turbulence. Even though adaptive optics has been recognized as a promising technology to improve image quality for a large aperture telescope, the question is often asked: "Is adaptive optics needed in a ground-based stellar interferometer?" In this paper, we develop the appropriate theory and provide simulation results to show why adaptive optics is needed in a ground-based optical interferometer. We also present a novel adaptive optics testbed including a tip-tilt error compensation system and a higher-order phase aberration compensation system to verify our theoretical simulation results.
