摘　　要：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 sunlight observation with each wavelength, aiming at the narrow spectrum test range and low spectral resolution weakness of solar radiation observation instrument, the optical system design scheme was proposed which can realize nanometer resolution based on applying spectral measurement technology. Combining with the characteristics of the sunlight and the service environment of the solar radiation observation instrument, the collecting light system was designed basing on fiber and cosine corrector. According to spectral range and spectral resolution, the spliting light system was designed with multi-channel and manometer resolution. Experimental and design results indicate that the spectral resolution precedes 20 nm and realizes the sunlight observation. It can satisfy the instrument requirements of wide spectrum and nanometer resolution.
