Applications of nonlinear and fractional diffusion processes tosignal processing in Raman spectroscopy

André Persechino


Raman Spectroscopy (RS) is a powerful analytical technique, based on the inelastic scatteringof light by the analyte. Its versatility lies on the fact that a wide range of materials can be analyzedin a non-destructive testing (NDT) fashion, ranging from bulk mineralogy to characterization ofhighly sensitive biological samples [6]. Despite such “universality”, Raman scattering cross-sectionis quite small, in such a manner signals are very often observed in noisy environments, accountingdifferent contributions, e.g. from fluorescence and CCD shot noise.
