In this work the potential mineral identification of meteorites is analysed for the mid-infrared range, to evaluate observational possibilities for future missions targeting small body surfaces. Three carbonaceous and three ordinary chondrite meteorites are examined by a diffuse reflection (DRIFT) instrument, and the presence of principal minerals is confirmed by a powder diffraction method as well. The possibilities and constraints of mineral identifications in the mid-infrared are simulated by artificially degrading the spectral resolution. Our research shows that for the definite identification of principal mineral bands, a spectral resolution $\leq 10$~cm$^{-1}$ ($\leq 0.15 \mu$m) is needed. At 20-100~cm$^{-1}$ (0.3 - 1.5~$\mu$m) resolution the identification of these minerals is uncertain, and with a resolution $>100$~cm$^{-1}$, it is almost impossible.

光谱分辨率在使用陨石光谱进行红外小行星成分分析中的作用

在这项工作中，分析了中红外范围内陨石的潜在矿物鉴定，以评估未来针对小体表的任务的观测可能性。三颗碳质陨石和三颗普通球粒陨石通过漫反射 (DRIFT) 仪器进行检测，主要矿物的存在也通过粉末衍射法确认。通过人为地降低光谱分辨率来模拟中红外矿物识别的可能性和限制。我们的研究表明，为了确定主要矿物带，需要光谱分辨率$\leq 10$~cm$^{-1}$ ($\leq 0.15 \mu$m)。在 20-100~cm$^{-1}$ (0.3 - 1.5~$\mu$m) 分辨率下，这些矿物的鉴定是不确定的，分辨率 $>100$~cm$^{-1}$ ,
