一米新真空太阳望远镜基于Fabry-Perot滤光器的高分辨观测系统研究

Fabry-Perot（F-P）滤光器可获得太阳二维成像光谱，具有很高的空间、时间和光谱分辨率，能够进行极窄带宽的高分辨率成像光谱观测，已经成为国外主要太阳望远镜的标准配置设备。而我国却没有F-P滤光器在太阳观测的实际应用。随着太阳物理的发展，观测者对成像光谱分辨率的要求不断提高，增强一米新真空太阳望远镜（NVST）的观测能力变得日益紧迫。本项目拟为NVST研制基于单级F-P滤光器的高分辨观测系统，通过对F-P滤光器的光谱性能、系统误差、测量精度和光谱稳定性等关键技术进行研究，分析并解决F-P滤光器实际应用过程中存在的问题，实现F-P滤光器在太阳观测的常规应用。.通过本项目的研究，F-P滤光器将成为NVST的关键设备，全面提高NVST的太阳观测能力，为下一个太阳活动峰年的科学观测做技术准备，对开展世界领先水平的太阳物理研究工作具有重要意义，同时也为研制下一代大型太阳望远镜提供必要的技术积累。

Fabry-Perot (F-P) Filter can obtain 2D imaging spectrum of solar with high spatial, temporal and spectral resolution, which can observe extremely narrow bandwidth of imaging spectrum. F-P Filter has become the standard equipment for major solar telescopes abroad. But there is no practical application of F-P Filter in solar observation in our country. With the development of solar physics, the requirement of imaging spectral observation is constantly increasing. So enhance the observation capability of the New Vacuum Solar Telescope (NVST) has become increasingly urgent. The project will develop high resolution observation system based on single F-P Filter for NVST. The spectral properties, system error, measurement precision and stability of F-P Filter will be research, and the problems existing in the practical application will be solved to make F-P Filter as routine observation equipment..The project will make F-P Filter become the key equipment of NVST, improve NVST solar observation ability, and prepare equipment for next maximum year of solar. It will promote solar physics research, and also offer necessary technology accumulation for next generation of large-scale solar telescope.
