LCTF成像光谱技术是近年来快速发展的一种成像光谱技术，具有光谱分辨率高、谱段范围宽、质量轻等诸多优点，在月球矿物探测高光谱成像遥感器中具有独特的优势。LCTF中液晶材料温度变化会引起双折射率偏差变大，从而影响LCTF光谱仪成像质量。通过对光谱仪工作环境的热分析，综合考虑光谱仪的工作模式及各部件工作温度要求，设计了LCTF光谱仪热控系统。仿真结果表明，该热控系统能较好地满足设计要求，使LCTF光谱仪清晰成像，为月球矿物探测做好硬件准备。

LCTF (Liquid Crystal Tunable Filter) is one of the rapid developing technologies in recent years. LCTF has many advantages, such as high spectral resolution, wide spectral range and light mass, so it is used widely in hyperspectral imaging remote sensor for lunar exploration. Various temperature in Liquid Crystal of LCTF will cause larger deviation of double refractive index, and that will affect the imaging quality of LCTF spectral imager. Working conditions of LCTF imaging spectrometer were analyzed in this paper. With the consideration about LCTF working modes and working temperature requirements, thermal control system was designed for LCTF spectral imager. The simulation results show that the designed thermal control system can meet the design requirements and LCTF spectral imager can get clear image to get ready for lunar exploration.
