论文摘要
准确的波长校准对于定性和定量光谱测量至关重要。许多用于行星探索的光谱仪配备了车载校准源。但是，这种校准来源并不总是可用的，因为行星着陆器任务通常在大小和质量方面存在强大的限制。在这项研究中，我们建议使用在反射光谱中观察到的太阳能Fraunhofer线进行波长校准方法。结果，对于可见的拉曼光谱仪，精度优于0-4000 cm-1范围内的0.6 cm-1，并且橄榄石的镁丰度估计比2％更准确。
Accurate wavelength calibration is critical for qualitative and quantitative spectroscopic measurements. Many spectrometers for planetary exploration are equipped with onboard calibration sources. However, such calibration sources are not always available because planetary lander missions often have strong limitations in size and mass. In this study, we propose and validate a wavelength calibration method using solar Fraunhofer lines observed in reflective spectra. As a result, for a visible Raman spectrometer, the accuracy is better than 0.6 cm-1 in 0-4000 cm-1 range, and the magnesium abundance of olivine is estimated more accurately than 2%.
