Definitions

  • Shown in FIG. 7 is a manually selected background (lower curve with square symbols) of the spectrum of FIG. 3 .
  • Automatic background removal for spectroscopic data saves user time, and plays an especially important role in rapid material identification, including, for example, spectral library searching and automated process control utilizing spectroscopy.
