  • Method and system removing fluorescence and other slowly varying baseline in Raman spectra
    Patent number: 7177022
    Abstract: A data set processing method for Raman spectroscopy systems using tunable lasers and multielement spectrometers compiles the spectral data set into an array and then estimates the background component, which is usually dominated by sample and optical train fluorescence, detector array dark current signal, fixed-pattern signal, and stray-light signals either modulated or non-modulated by in-path optics. This estimate is used as a baseline correction to the spectral data set to thereby isolate the sample's Raman response.
