在天文学家可用的自适应光学系统中，美国空军先进光电系统(AEOS)是独一无二的，因为它提供非常高阶波前校正。Lyot项目包括建造和安装世界上第一台衍射受限、优化的日冕仪，它充分发挥了AEOS的天文潜力，代表着朝着直接成像和研究太阳系外行星(也称为太阳系外行星)的长期目标迈出了关键的一步。“系外行星”)。我们提供了该项目的最新情况，该项目的日冕图于2004年3月首次亮相。日冕仪的运行至少和模拟预测的一样好，对附近恒星的调查已经开始。
Among the adaptive optics systems available to astronomers, the US Air Force Advanced Electro-Optical System (AEOS) is unique because it delivers very high order wave front correction. The Lyot Project includes the construction and installation of the world’s first diffraction-limited, optimized coronagraph that exploits the full astronomical potential of AEOS and represents a critical step toward the long-term goal of directly imaging and studying extrasolar planets (a.k.a. “exoplanets”). We provide an update on the Project, whose coronagraph saw first light in March 2004. The coronagraph is operating at least as well as predicted by simulations, and a survey of nearby stars has begun.
