自适应光学（AO）是一种用于地面天文学的技术，用于校正大气湍流引起的波前像差和像质损失。如果能够克服一些技术难题，未来天文学家将能够利用目前正在研制的超大望远镜实现接近衍射极限的性能，从而大大提高空间分辨率、光谱分辨率和观测效率。这篇专题综述的目的是向反问题社区提供这些问题的代表性样本。在这篇综述中，我们首先介绍了当前AO系统中使用的数学模型和技术的教程概述。然后，我们详细研究了以下主题：激光导星自适应光学，多共轭和多目标自适应光学，高对比度成像和可变形镜建模和参数识别。
Adaptive optics (AO) is a technology used in ground-based astronomy to correct for the wavefront aberrations and loss of image quality caused by atmospheric turbulence. Provided some difficult technical problems can be overcome, AO will enable future astronomers to achieve nearly diffraction-limited performance with the extremely large telescopes that are currently under development, thereby greatly improving spatial resolution, spectral resolution and observing efficiency which will be achieved. The goal of this topical review is to present to the inverse problems community a representative sample of these problems. In this review, we first present a tutorial overview of the mathematical models and techniques used in current AO systems. We then examine in detail the following topics: laser guidestar adaptive optics, multi-conjugate and multi-object adaptive optics, high-contrast imaging and deformable mirror modeling and parameter identification.
