  "term": "Interferogram",
  "field": "Chemistry",
  "definition": "A plot of the intensity of radiation detected by an interferometer as a function of the optical path difference between two beams. This raw signal contains all the spectral information in an encoded form. A mathematical operation, typically a Fourier transform, is applied to convert the interferogram into a conventional spectrum.",
