System and Method for Combined Raman and LIBS Detection

A system comprising:

• an illumination source, wherein said illumination source is configured to illuminate at least one of:
• a first region of a sample to thereby generate a first plurality of interacted photons and a second region of said sample to thereby generate a second plurality of interacted photons;
• a fiber array spectral translator device, wherein said device comprises a two-dimensional array of optical fibers drawn in into a one-dimensional fiber stack so as to effectively convert a two-dimensional field of view into a curvilinear field of view and,
• a Raman spectrometer wherein said Raman spectrometer is configured so as to effectively separate said first plurality of interacted photons into a first plurality of wavelength bands;
• a LIBS spectrometer wherein said LIBS spectrometer is configured so as to effectively separate said second plurality of interacted photons into a second plurality of wavelength bands;
• a Raman detector to thereby generate a Raman data set representative of said first region;
• and
• a LIBS detector to thereby generate a LIBS data set representative of said second region of said sample.

A method comprising:

• illuminating a first region of a sample to thereby generate a first plurality of interacted photons;
• illuminating a second region of said sample to thereby generate a second plurality of interacted photons;
• passing said first plurality of interacted photons and said second plurality of interacted photons through a fiber array spectral translator device;
• detecting said first plurality of interacted photons using Raman gated detection to thereby generate at least one Raman data set representative of said first region of said sample;
• and
• detecting said second plurality of interacted photons using LIBS gated detection to thereby generate at least one LIBS data set representative of said second region of said sample.
