Raman spectroscopy system, apparatus, and method for analyzing, characterizing, and/or diagnosing a type or nature of a sample or a tissue such as an abnormal growth
Characterizing, identifying, or diagnosing the type and/or nature of a sample or a tissue such as an abnormal growth using a Raman spectrum includes analyzing distinct spectral subintervals within the Raman spectrum in two distinct wavelength ranges, such as FP and HW wavelength ranges, to identify a match with one or more reference markers in one or both wavelength ranges and from the match characterizing, identifying, or diagnosing the type and/or nature of the sample or tissue. FP and HW Raman spectra can be detected or acquired simultaneously using a single diffraction grating.
