Design and preliminary verification of asteroid thermal emission spectrometer for Tianwen-2

热辐射光谱仪作为我国首个小天体探测任务(天问二号)的科学载荷之一,主要工作为获取近地小行星2016 HO3和主带彗星311P的表面热辐射光谱,研究表面的热辐射特性和矿物质分布;获取小行星表面热物理参数用于热模型反演,支持采样任务。光谱仪的谱段范围覆盖5 - 50 μm,光谱分辨率为9.79 cm-1,信噪比优于326 (7.5 - 35 μm @325 K),角分辨率为3.28 mrad × 3.29 mrad,重量小于10 kg。采用双角镜、四端口、时间调制型干涉分光技术,创新性地利用目标和参考两路输入的光学相减,有效提升探测灵敏度和动态范围。本文介绍了热辐射光谱仪的工作原理、技术特点以及地面测试与初步验证情况,可为同类载荷研制提供参考。

Abstract

热辐射光谱仪作为我国首个小天体探测任务(天问二号)的科学载荷之一,主要工作为获取近地小行星2016 HO3和主带彗星311P的表面热辐射光谱,研究表面的热辐射特性和矿物质分布;获取小行星表面热物理参数用于热模型反演,支持采样任务。光谱仪的谱段范围覆盖5 - 50 μm,光谱分辨率为9.79 cm-1,信噪比优于326 (7.5 - 35 μm @325 K),角分辨率为3.28 mrad × 3.29 mrad,重量小于10 kg。采用双角镜、四端口、时间调制型干涉分光技术,创新性地利用目标和参考两路输入的光学相减,有效提升探测灵敏度和动态范围。本文介绍了热辐射光谱仪的工作原理、技术特点以及地面测试与初步验证情况,可为同类载荷研制提供参考。
