AI 中文摘要
XuYi 干涉仪是中国科学院国家天文光学技术研究所（NIAOT）正在研发的首台中国长基线光学干涉仪。为筹备未来的科学运行，我们开发了 XuYi 干涉仪观测模拟器（XIOS），这是一个基于 MATLAB 的轻量级软件包，旨在协助观测者规划干涉观测。该模拟器将目标可观测性计算、干涉基线几何、延迟线约束、（u,v）覆盖预测以及可见度估计整合到一个图形用户界面中。它采用了 MAAT 工具箱中的天文例程，并借鉴了 ASPRO2 的可视化概念。该软件允许用户在望远镜运行之前评估观测机会、预测干涉性能并生成现实的观测配置。我们展示了该模拟器的架构、其主要模块以及针对当前三望远镜 XuYi 干涉配置在近红外 H 波段运行所获得的代表性模拟结果。
英文摘要
The XuYi Interferometer is the first Chinese long-baseline optical interferometer currently under development by the National Institute of Astronomical Optics and Technology (NIAOT) of the Chinese Academy of Sciences. In preparation for future scientific operations, we developed the XuYi Interferometer Observation Simulator (XIOS), a lightweight MATLAB-based software package designed to assist observers in planning interferometric observations. The simulator combines target observability calculations, interferometric baseline geometry, delay-line constraints, (u,v)-coverage prediction, and visibility estimation into a single graphical user interface. It incorporates astronomical routines from the MAAT toolbox and adopts visualization concepts inspired by ASPRO2. The software allows users to evaluate observing opportunities, predict interferometric performances, and generate realistic observing configurations before telescope operations. We present the architecture of the simulator, its principal modules, and representative simulation results obtained for the current three-telescope XuYi interferometric configuration operating in the near-infrared H band.
