发布时间：2018-11-11 15:09
【摘要】：1米新真空太阳望远镜(NVST)是目前国内最大的太阳望远镜,主要对太阳光球和色球进行高空间分辨率的成像观测和高光谱分辨率的光谱观测。其中,多通道高分辨成像系统是重要终端之一,目前已经实现了TiO和Hα双通道高分辨观测系统。该系统利用天文高分辨图像处理技术消除湍流大气对成像质量的影响,能够对太阳光球和色球进行同步高分辨率的观测。本文主要内容为根据多通道高分辨成像系统的需求,设计并实现了多通道高分辨观测软件。该软件在功能上针对双通道不同观测方式实现了相对应的课题和常规观测模式,包括Hα通道单个波长点观测和多个波长点扫描观测模式,TiO通道高时间分辨率和多时间分辨率观测模式。由于多通道成像系统仍处于发展阶段,需要观测系统具有良好的可扩展性,因此系统体系结构采用了分布式、多终端的系统部署方式和松耦合的软件架构。其中,软件架构借鉴了ACS(ALMA Common Software)的做法,采用了顶层架构以及基于容器组件的技术/功能架构,降低功能与功能之间、功能与具体实现技术间的耦合性。本文第一章介绍了NVST及双通道观测采集软件的历史以及当前国内外观测采集软件的相关调研。文章第二、第三部分主要分析双通道当前观测需求以及多通道发展对观测采集软件的非功能性需求。文章第四部分描述由多通道高分辨成像系统需求所采用的相应设计思路,包括系统体系结构和软件架构。第五部分为软件架构的具体实现。第六部分为观测系统展望。
[Abstract]:The 1-meter vacuum solar telescope (NVST) is the largest solar telescope in China at present. The solar sphere and color sphere are mainly observed with high spatial resolution imaging and high spectral resolution. Multi-channel high-resolution imaging system is one of the most important terminals. At present, TiO and H 伪 dual-channel high-resolution observation system has been realized. The system uses astronomical and high-resolution image processing technology to eliminate the influence of turbulent atmosphere on imaging quality, and can perform synchronous high-resolution observation of solar and color spheres. The main content of this paper is to design and implement the multi-channel high-resolution observation software according to the demand of multi-channel high-resolution imaging system. The software realizes the corresponding subject and conventional observation mode for different observation modes of two channels, including single wavelength point observation of H 伪 channel and scanning observation mode of multiple wavelength points. TiO channel high time resolution and multi-time resolution observation mode. Because the multi-channel imaging system is still in the developing stage and the observation system has good scalability, the system architecture adopts distributed, multi-terminal system deployment and loosely coupled software architecture. The software architecture adopts the top-level architecture and the technology / function architecture based on container components to reduce the coupling between function and concrete implementation technology. The first chapter of this paper introduces the history of NVST and dual channel observation and acquisition software, and the related investigation of domestic and foreign observation acquisition software. In the second and third part, we analyze the current observation requirements of two channels and the non-functional requirements of multi-channel development for observation and acquisition software. The fourth part of the paper describes the corresponding design ideas adopted by the requirements of multi-channel high-resolution imaging system, including system architecture and software architecture. The fifth part is the realization of software architecture. The sixth part is the prospect of observation system.
