Fourier transform spectrometer

  "term": "Fourier transform spectrometer",
  "field": "Chemistry",
  "definition": "A spectrometer built around a scanning interferometer, usually of the Michelson type, with no dispersive element such as a prism or grating. It splits the beam, recombines the parts with a variable path difference and records the resulting interferogram, which a Fourier transform converts into a spectrum. All wavelengths are measured at once, so the design gives a high signal-to-noise ratio and dominates infrared work as the FTIR spectrometer.",
