Comparison of different kinds of skin using Raman spectroscopy

In this work we developed a novel technique to remove the fluorescence background in the Raman spectrum. This technique permit us to obtain better accuracy in the spectrum peaks, it is based in the wavelets theory, using symlets and biothogonals wavelets, therefore it is adapting with the Raman Spectrum. We use a spectral range from 300 to 1800(cm(-1)), 785 nm laser excitation source and Oceans optics spectrometer was used. The experimental samples were people with different kinds of skin, like brown, black and white. We compare the differences between each Raman spectra, which permitted us to identified persons due to accuracy of Raman spectroscopy. This results shows that Raman spectroscopy has greatly precision in this field of biomedical optics.
