Adaptive optics is a term related to the technology used in astronomical telescopes and laser systems. It is a mechanism that helps in reducing the blurring effect caused by the Earth's atmosphere during astronomical observations. There are several synonyms that can be used to describe adaptive optics, such as wavefront correction, active optics, real-time correction, optical phase manipulation, and deformable mirrors. Each of these terms describes the function of adaptive optics in a specific way, but they all share the common feature of correcting for the distortions caused by turbulence in the atmosphere. The use of adaptive optics has revolutionized astronomical research by allowing for clearer images and more accurate observations of celestial objects.
