Spectral imaging

Spectral imaging combines spectroscopy with imaging, two widespread methodologies, thus generating advantages that cannot be obtained separately by imaging or spectroscopy alone. The spectral content of a sample provides important information that  cannot  be  detected  by  the  human  eye  or  by  using  an  ordinary  RGB camera. The spectrum is typically a fingerprint of the chemical compound, its environmental conditions, phase and geometry.  Thus measuring the spectrum  at  each  point  of  a  sample  is  important  for  a  large  range  of applications from art preservation through forensics to pathological analysis of a tissue section.
