Application of thermal/structural/optical integrated analysis to ultraviolet lens of hyperspectral imaging spectrometer

  • 摘要: 温度变化会影响紫外镜头各镜面面形和镜片间隔的变化,采用了光机热集成分析方法研究温度对紫外镜头成像质量的影响。论述光机热集成分析的基本流程和关键技术,采用Zernike多项式作为结构分析与光学分析之间的接口工具,在紫外镜头光学系统设计和机械结构设计的基础上,建立了紫外镜头的热结构分析模型,得到各镜面面形和镜片间隔的变化结果,并将结果耦合到光学设计软件中进行像质分析。分析结果表明,在镜头的工作范围内,镜头的调制传递函数在12 lp/mm处均在0.7左右,能满足高光谱成像光谱仪的使用要求,同时也为光谱仪最后整机分析提供了参考。
    Abstract: The temperature change can affect the change of the shape and interval of the surfaces of the ultraviolet(UV) lens. In order to study the effect of the temperature on the imaging quality of the UV lens, the method of thermal/structural/optical(TSO) integrated analysis was used. The basic processes and key technologies of the TSO integrated analysis were discussed and the Zernike polynomials was used as the interface between structural analysis and optical analysis. Based on the design of the optical system and mechanical structure of the UV lens, the thermal-structural model of the lens was established and the changes of the surface shape and lens spacing were obtained. Finally, the results were coupled in the optical design software, then the image quality was further analyzed. The analysis results show that, in the working range of the lens, the design value of the modulation transfer function (MTF) at 12lp/mm is about 0.7, which can meet the use requirements of hyperspectral imaging spectrometer. At the same time, it also provides a reference for the analysis of the final machine of the spectrometer.
