Patent ID: 7808634

Claim:
A system for simultaneous calibration and dispersive and/or spectral imaging of a sample comprising: an input for simultaneously receiving a first plurality of Raman scattered photons collected from the sample and a second plurality of Raman scattered photons collected from an intrinsic calibrant, wherein said first plurality of Raman scattered photons and said second plurality of Raman scattered photons originate from the same source; a spectrometer for forming a sample Raman spectrum from the first plurality of Raman scattered photons and a calibrant Raman spectrum from the second plurality of Raman scattered photons; a first processor for comparing the calibrant Raman spectrum with a reference Raman spectrum of the calibrant to determine a Raman-shift in the calibrant Raman spectrum; a second processor for applying the Raman-shift to the sample Raman spectrum to obtain a calibrated sample Raman spectrum; and a means for forming a spatially accurate wavelength resolved Raman image of said sample.
