摘要
大面阵红外探测器是地面和空间大型天文仪器的核心，其中 HgCdTe HxRG 是应用最广泛的。欧空局 (ESA) 于 2023 年 7 月发射的 Euclid 任务的近红外光谱仪和光度计 (NISP) 在其焦平面上配备了 16 个 H2RG 探测器。它们的性能在很大程度上受到图像持久性效应的影响，该效应会导致残余图像长期残留在探测器中，从而污染后续的任何观测。由于这种效应对数小时甚至数天前的观测历史非常敏感，因此推导精确的图像持久性模型极具挑战性。尽管如此，持久性去除仍是图像处理的关键部分，因为它限制了所推导宇宙学参数的准确性。我们将展示基于地面表征数据推导出的图像持久性经验模型，该模型已适应 Euclid 观测序列，并与卫星在轨校准期间获得的数据进行了比较。
