Rapid spectral analysis for spectral imaging [PDF]
Biomedical Optics Express, 2010 Spectral imaging requires rapid analysis of spectra associated with each pixel. A rapid algorithm has been developed that uses iterative matrix inversions to solve for the absorption spectra of a tissue using a lookup table for photon pathlength based on numerical simulations.
