AI 中文摘要
中红外极端大望远镜成像仪和光谱仪（METIS）是极大望远镜（ELT）的首批初光仪器之一，其L和M波段采用的Teledyne H2RG探测器存在电荷迁移现象，即亮像素效应（BFE）。在H2RG探测器中，该现象表现为光电子从中心亮像素向相邻像素移动，原因是中心像素的耗尽区随累积电荷收缩。由于其会模糊信息，尤其影响直接成像、凌星和高分辨率光谱学应用。本研究旨在表征METIS H2RG探测器中的该效应，以便在不丢失信息的前提下对其进行校正。
英文摘要
The Mid-infrared ELT Imager and Spectrograph (METIS) is one of the first-light instruments of the Extremely Large Telescope (ELT). For the L and M band, the instrument makes use of Teledyne's H2RG detectors, known to be affected by charge migration, also known as the brighter-fatter effect (BFE). In the H2RG detectors this manifests as photo-electrons moving from a central bright pixel to neighboring pixels as the depletion region of the central pixel shrinks with accumulated charge. Due to its effect of `blurring' information, it especially affects direct imaging, transit, and high-resolution spectroscopy applications. We aim to characterize its effect in the METIS H2RG detectors, such that we can remove it without losing information.
