Adaptive optics

Definition

Adaptive optics is a technology used in telescopes to improve image quality by compensating for distortions caused by Earth's atmosphere. It involves real-time adjustments of optical components to correct wavefront errors.

5 Must Know Facts For Your Next Test

1. Adaptive optics significantly enhances the resolution and clarity of ground-based telescopes.
2. The system uses deformable mirrors controlled by computers to counteract atmospheric distortions.
3. Wavefront sensors detect incoming light distortions, which are then corrected by the adaptive optics system.
4. Adaptive optics can enable ground-based telescopes to achieve near space-based telescope performance.
5. This technology is crucial for observing fine details in astronomical objects like stars and planets.
