Abstract The focus of this paper is to study the application of the first order derivative method for the estimation of minerals rates in different mineral mixtures. The primary goal with this is to find robust spectral features of specific minerals that are not severely influenced by the spectral features of the other minerals in a mixture. Results were used to select appropriate spectral features to be applied for quantifying the minerals in upcoming studies. Mixtures of different terrestrial minerals equivalent to those dominating the Martian surface with a grain size

一阶导数反射光谱在 VNIR-SWIR 中量化橄榄石和赤铁矿的优势

摘要 本文的重点是研究一阶导数法在不同矿物混合物中矿物比率估计中的应用。这样做的主要目标是找到不受混合物中其他矿物光谱特征严重影响的特定矿物的稳健光谱特征。结果用于选择适当的光谱特征，用于在即将进行的研究中量化矿物。不同陆地矿物的混合物，相当于那些在火星表面占主导地位的具有颗粒大小的矿物
