Abstract: (1831 Views)
Reflection spectroscopy is a non-destructive and fast technique based on optical principles. The spectral range used in this study is in the near infrared region. Most of the organic compounds and part of the mineral compounds absorb the frequencies in the infrared region. We perform a spectroscopy experiment on 27 samples of the soils which have been chemically analysed in the soil labs. In a MATLAB program, we use a continuum removal on the spectra from the reflection process, perform pre-processing techniques, and reach a particular pattern by comparing the resultant spectra and the concentration of clay and calcium carbonate in the samples. The pattern can help measure the above two soil properties in the new samples using reflection spectroscopy.
