极端自适应光学系统（SAXO）是SPHERE仪器的核心，旨在从地面直接探测和表征巨大的太阳系外行星。它将在2010年底装备4个VLT 8米望远镜中的一个。我们提出了SAXO系统的详细设计和体系结构。我们专注于在初步设计阶段已经解决的每个关键点。它涉及自适应光学系统本身，但也与其他SPHERE子系统（如日冕）和焦平面仪器（双波段成像仪，积分场光谱和偏振成像仪）的相互作用。讨论了SAXO的验收和集成测试。最后给出了整个系统的详细性能，并与科学要求进行了比较。
Extreme adaptive optics system (SAXO) is the heart of the SPHERE instrument which aims at directly detect and characterize giant extra-solar planets from the ground. It should equip one of the four VLT 8-m telescopes at the end of 2010. We present a detailed design and architecture of the SAXO system. We focus on each critical point that has been solved during the preliminary design phase. It concerns the adaptive optics system itself but also the interaction with other SPHERE subsystems (such as coronagraphy) and focal plane instrumentation (dual band imager, integral field spectroscopy and polarimetric imager). Acceptance and integration tests of SAXO are discussed. Finally, detailed performance of the whole system and comparison to the science requirements are provided.
