The basic principle of Adaptive Optics is the real-time correction of wavefront aberrations or distortions that arise from atmospheric disturbances or object motion.
Generically, adaptive optics is defined as an optical system in which controllable and movable optical elements optimize the performance of the system in the presence of wavefront error. Imaging distortions from atmospheric disturbance or object motion are the typical sources of wavefront error. AO systems correct wavefront error in a high speed closed loop control system, resulting in highly responsive, dynamic optical performance improvements.
