为了实现太阳光各波长下观测,针对现有的太阳辐射观测仪光谱测试范围窄、光谱分辨率低的缺点,提出了一种运用光谱测量技术实现高分辨率太阳观测仪光学系统的设计方案。结合太阳辐射观测仪的使用环境与太阳光的特点,利用光纤、余弦校正器等器件设计了太阳辐射观测仪的收光系统。根据太阳光的光谱范围以及光谱分辨率的要求,设计了多通道、高分辨率的太阳辐射观测仪分光系统。实验与设计结果表明:光谱分辨率优于20 nm,能够实现太阳的光谱观测。满足太阳辐射观测仪宽光谱、纳米分辨率等要求。
In order to realize the observation of solar radiation at various wavelengths, aiming at the shortcoming of narrow range of spectral measurement and low spectral resolution of existing solar radiation observers, a design scheme of optical system for high resolution solar observer using spectral measurement technology is proposed. Combined with the use of solar radiation observer environment and the characteristics of sunlight, the use of optical fiber, cosine corrector and other devices designed solar radiation observer’s light-receiving system. According to the spectral range of sunlight and the requirements of spectral resolution, a multi-channel and high-resolution solar radiation observer spectroscopy system is designed. Experiments and design results show that the spectral resolution is better than 20 nm and the solar spectrum can be observed. Meet the solar radiation observer wide spectrum, nano-resolution and other requirements.
