论文摘要
ERIS是非常大的望远镜UT4的衍射有限的热红外成像仪和光谱仪。 ERIS的科学案例之一是对明亮恒星周围的间隔结构和系外行星的检测和表征，通常比恒星衍射光晕。通过（i）使用冠状动脉抑制（i）抑制目标恒星的衍射光环的组合，以及（ii）通过焦平面波前传感和随后的主动校正去除任何残留的衍射结构，提供了增强的灵敏度。在本文中，我们介绍了用于衍射抑制的两个冠状动脉，并在ERI中实现了高对比度成像。
ERIS is a diffraction limited thermal infrared imager and spectrograph for the Very Large Telescope UT4. One of the science cases for ERIS is the detection and characterization of circumstellar structures and exoplanets around bright stars that are typically much fainter than the stellar diffraction halo. Enhanced sensitivity is provided through the combination of (i) suppression of the diffraction halo of the target star using coronagraphs, and (ii) removal of any residual diffraction structure through focal plane wavefront sensing and subsequent active correction. In this paper we present the two coronagraphs used for diffraction suppression and enabling high contrast imaging in ERIS.
