摘要: 高光谱分辨率光栅光谱仪是探测太阳大气活动的重要仪器。由于光栅衍射效率受光栅入射角的影响, 从 而直接影响光栅光谱仪的能量利用率, 因此如何准确确定光栅入射角是光栅光谱仪光学设计面临的重要问题之一, 现有方法多依靠工程实践积累的经验。为此, 以多个特征谱线均能获得更高光栅衍射效率为优化指标, 以光栅入 射角为研究对象, 提出了一种高光谱分辨率光栅光谱仪的优化设计方法, 并给出了针对云南天文台1 m 新真空太 阳望远镜(NVST) 的多波段光栅光谱仪设计方案。

Abstract: Grating spectrometer with high spectral resolution is an important tool for detecting solar atmospheric activities. As the grating diffraction efficiency is affected by the grating incidence angle, which directly affects the energy utilization of grating spectrometer, how to accurately determine the incident angle of grating is one of the important problems in the optical design of grating spectrometer. The current methods mostly depend on the experience accumulated from engineering practice. In view of this situation, taking that multiple characteristic spectral lines can obtain higher grating diffraction efficiency as the optimization index, and taking the grating incident angle as the research object, an optimal design method for high-spectral resolution grating spectrometer is proposed, and the design of high spectral resolution solar grating spectrometer for 1m new vacuum solar telescope (NVST) in Yunnan observatory is given.

Key words: spectroscopy, grating spectrometer, high spectral resolution, grating incidence angle, grating diffraction efficiency
