Adaptive optics

Definition

Adaptive optics is a technology used in optical systems to improve image quality by correcting for distortions caused by atmospheric turbulence or imperfections in the optical components. It involves the use of a deformable mirror and wavefront sensors to dynamically adjust the shape of the mirror in real-time, compensating for any aberrations and allowing for clearer imaging at high resolutions. This technique is particularly useful in applications like astronomy and microscopy, where precise observation of small structures is critical.
