Reconstructing Turbulence-Distorted Wavefronts Through Laser-Beam Profiles
摘要
Adaptive optics (AO) compile a variety of techniques that produce high-quality images in ground-based telescopes. Most commonly used AO techniques require the use of laser guide stars, which introduce errors due to the limited width and low altitude of these artificial stars, resulting in issues such as anisoplanatism and cone-effect problems. This study proposes an alternative AO system that aims to eliminate these issues. In contrast with similar techniques such as the Projected Pupil Plane Pattern (PPPP), that uses two pictures, Wavefronts Obtained from Measurements from Beam-profiles through Atmospheric Turbulence (WOMBAT) requires only one picture, reducing the complexity of the system. Even with only one image, WOMBAT manages to achieve similar results to PPPP in wavefront correction, offering potential advancements in ground-based telescope imaging quality.
