Keyword1 m新真空太阳望远镜 光谱扫描观测 光谱仪切换 性能测试

1 m新真空太阳望远镜(New Vacuum Solar Telescope, NVST)的科学目标之一是对太阳活动区域进行二维光谱扫描观测。基于1 m新真空太阳望远镜多波段光谱仪(Multi-Band Spectrometer, MBS)和大色散光谱仪(High Dispersion Spectrometer, HDS)提出了垂直双光谱切换扫描系统,可实现相互垂直的两个光谱仪的光谱扫描观测任务,并实现两个光谱仪之间的切换。分析了光谱扫描观测的原理和过程,结合终端仪器系统的具体构造,完成了扫描系统的光机结构设计和装调分析,并对扫描系统进行了性能测试,包括系统稳定性、扫描直线度以及扫描步幅精度。测试结果满足预期功能需求和精度要求,为后续1 m新真空太阳望远镜进行常规光谱扫描观测提供了支持。

Other Abstract

One of NVST′s scientific goals is to perform two⁃dimensional spectral scanning observations of solar active regions. Based on NVST′s Multi⁃Band Spectrometer and High Dispersion Spectrometer, this paper proposes a switching and spectral scanning system of the vertical double spectrometer, which can realize the spectral scanning observation tasks of two mutually perpendicular spectrometers and participate in the realization of switching between the two spectrometers. The principle and process of spectral scanning observation is analyzed. Combined with the specific structure of the NVST′s terminal instrument system, the optical⁃mechanical structure design and installation of the system are completed. And the performance test of the system is performed, including system stability, scanning straightness and scanning step accuracy test. The test results meet the expected functional requirements and accuracy requirements. The work can provide support for NVST to perform conventional spectral scanning observations.
