Abstract
Tortuosity, as a transformation of near-infrared spectra, is illustrated in this communication. To overcome the loss of any grouping structure, due to substrate-sample treatment or different particle size effects, a new autoregression scatter correction is described that preserves such stratification. Tortuosity applications are well established in medical, engineering and diffusion studies. Herein, tortuosity application to near-infrared diffuse reflectance spectra is presented as an additional tool for spectral change investigations.
