Abstract

For time-domain astronomy, it is crucial to frequently image celestial objects at specific depths within a predetermined cadence. To fulfill these scientific demands, scientists globally have started or planned the development of non-interferometric telescope arrays in recent years. Due to the numerous parameters involved in configuring these arrays, there is a need for an automated optimization framework that selects parameter sets to satisfy scientific needs while minimizing costs. In this paper, we introduce such a framework, which integrates optical design software, an exposure time calculator, and an optimization algorithm, to balance the observation capabilities and the cost of optical telescope arrays. Neural networks are utilized to speed up results retrieval of the system with different configurations. We use the SiTian project as a case study to demonstrate the framework’s effectiveness, showing that this approach can aid scientists in selecting optimal parameter sets. The code for this framework is published in the China Virtual Observatory PaperData Repository, enabling users to optimize parameters for various non-interferometric telescope array projects.

一种用于巡天的大视场小口径望远镜阵列优化框架
对于时域天文学来说,在预定的节奏内频繁地对特定深度的天体进行成像是至关重要的。为了满足这些科学需求,近年来,全球科学家已经开始或计划开发非干涉望远镜阵列。由于配置这些阵列涉及众多参数,因此需要一个自动优化框架来选择参数集以满足科学需求,同时将成本降至最低。在本文中,我们介绍了一个集成光学设计软件、曝光时间计算器和优化算法的框架,以平衡光学望远镜阵列的观测能力和成本。利用神经网络来提高系统在不同配置下的检索速度。我们以四田项目为例,证明了该框架的有效性,表明该方法可以帮助科学家选择最优参数集。该框架的代码发布在中国虚拟天文台论文数据库中,使用户能够优化各种非干涉望远镜阵列项目的参数。

期刊介绍: Many new instruments for observing astronomical objects at a variety of wavelengths have been and are continually being developed. Furthermore, a vast amount of effort is being put into the development of new techniques for data analysis in order to cope with great streams of data collected by these instruments. Experimental Astronomy acts as a medium for the publication of papers of contemporary scientific interest on astrophysical instrumentation and methods necessary for the conduct of astronomy at all wavelength fields. Experimental Astronomy publishes full-length articles, research letters and reviews on developments in detection techniques, instruments, and data analysis and image processing techniques. Occasional special issues are published, giving an in-depth presentation of the instrumentation and/or analysis connected with specific projects, such as satellite experiments or ground-based telescopes, or of specialized techniques.
