摘要
设计了利用高空气球平台搭载到达临近空间底部区域的太阳远紫外-紫外光谱仪,对170~400 nm波段的太阳远紫外-紫外辐射进行高分辨光谱探测,在该区域获得波长小于280 nm的远紫外光谱数据。该远紫外-紫外光谱仪采用改进的罗兰圆光路设计实现紧凑、轻量化、宽波段和高光谱分辨率,并通过Zemax仿真软件对光路设计进行了光谱分辨率、波段覆盖性和杂散光抑制等关键指标的仿真分析,验证设计的可实现性及其对科学研究需求的满足度。
A high spectral-resolution solar Far-Ultravoilet/Ultraviolet(FUV/UV)spectrometer carried by high-altitude balloons to the bottom region of the near space was designed,which will historically fill the data gap in wavelength shorter than 280 nm that deposits engergy in this region.The solar FUV/UV spectrometer is based on improved Roland circle optics.In order to adapt to the requirements of highaltitude balloon platforms,it has a compact design for the optics to reduce the dimensions of the instrument,to suppress the spherical aberration of the optical system,and to improve the quality of the spectrum.The optical performance was simulated by the Zemax software to analyze the spectral resolution,wavelength coverage,and stray light suppression.
