Research on the characteristics of strong linearly related bands based on derivative of ratio spectroscopy


Abstract:
The spectra of mineral powder and mineral rock were compared and analyzed.A quantitative inversion based on DRS was performed on powder mixtures of plaster and allochite to extract the strong linear bands of each component separately.Combining with the absorption characteristics of endmember minerals,the distribution characteristics of strong linear bands on the reflectance spectra,the ratio spectra and the derivative of ratio spectra were discussed.

Key words:spectral unmixing,strong linear bands,derivative of ratio spectroscopy,quantitative analysis of minerals
