What specific atmospheric interference do adaptive optics systems on ground-based telescopes actively correct for?
Answer
The blurring effects caused by Earth's turbulent atmosphere
Ground-based telescopes, despite their massive light-gathering potential, suffer from a fundamental limitation imposed by their location on Earth: atmospheric turbulence. This constant churning of air causes incoming starlight to wobble and blur by the time it reaches the mirror surface. Adaptive optics systems are sophisticated technologies employing deformable mirrors that rapidly change shape based on real-time measurements. This active reshaping precisely counteracts the distortion caused by atmospheric fluctuations, allowing ground stations to achieve far sharper images approaching the theoretical limits set by the telescope's aperture size.
