Adaptive optics

Definition

Adaptive optics is a technology used to improve the performance of optical systems by compensating for distortions caused by the atmosphere or other factors. This technique adjusts the optical elements in real time, allowing for clearer images and enhanced resolution, which is particularly important in advanced imaging techniques and in studying biological tissues.
