This paper provides a comprehensive review of Adaptive Optics (AO) technology for large aperture astronomical optical telescopes, including both night-time and day-time solar optical telescopes. It covers recent technological advances such as Laser Guide Star (LGS), Deformable Secondary Mirror (DSM), Extreme AO (ExAO), and Multi-Conjugate AO (MCAO). The introduction highlights the historical development of AO, from its inception in 1953 to its current applications in major telescopes. The paper discusses key AO technologies, including deformable mirrors (DMs), wavefront sensors (WFS), and guide stars (GSs). It also details the architecture and performance of typical AO systems, such as traditional AO, LGS AO, DSM AO, and ExAO. The paper further explores the development of wide field AO technology, including MCAO, Ground Layer AO (GLAO), and Multi-Object AO (MOAO), and their applications in solar observations. Finally, it describes the current state of AO systems at three 30m class extremely large telescopes and two 4m solar telescopes, emphasizing the advancements in AO technology and its impact on astronomical observations.This paper provides a comprehensive review of Adaptive Optics (AO) technology for large aperture astronomical optical telescopes, including both night-time and day-time solar optical telescopes.
