摘要
本文针对光谱分辨率对矿物识别的影响进行了实验,在 JPL-1光谱库中选择了6种含不同离子团的矿物光谱曲线,利用 ENV14.2对其进行重采样,模拟不同光谱分辨率条件下得到的光谱曲线.分别运用图示和 SAM 法进行定性和定量的分析,并将重采样的物质特征光谱在不同的光谱范围内与原光谱进行比较,通过分析各种矿物不同光谱分辨率条件下的光谱特征,得到的模拟实验结论,可以为用于地质调查的成像光谱仪在光谱分辨率的确定和优化等方面提供理论基础和技术支持。
Six spectral curves of the minerals containing different ions are chosen from the JPL-1 spectral library and are resampled by using the ENVI4.2,in order to simulate the spectral curves acquired under conditions of the different spectral resolution.The simulating results analyzed with the SAM are similar to the theoretical analysis. Through analyzing the differences between the original spectral curve and the spectral curves acquired by resampled, the qualitative and quantitative conclusions are given,and the influence of spectral resolution on the mineral recognition is shown.The result can help to fix on the spectral resolution when the imaging spectrometer was designed.
