Fourier-transform spectroscopy - Wikipedia
Fourier-transform spectroscopy is a measurement technique whereby spectra are collected based on measurements of the coherence of a radiative source, using time-domain or space-domain measurements of the radiation, electromagnetic or not.
The Power of the Fourier Transform for Spectroscopists
2023年1月30日 · By definition, Fourier transform spectroscopy is a spectroscopic technique where interferograms are collected by measurements of the coherence of an electromagnetic radiation source in the time-domain or space-domain, and translated into frequency domain through Fourier transform.
Equations (8) and (9) are known as the cosine-form of the Fourier transform. equation, or of the Fourier integral. There are a great many Fourier transform pairs, and each is unique. However, only a few simple, commonplace functions are cogent here and need to.
An interferometer invented by A. A . Michelson is used in a method called Fourier transform spectroscopy. The interferometer processes radiant energy into a Fourier transform of the spectrum which is then inverted by a digital computer.

Fourier-transform spectroscopy (Becker & Farrar, 1972; Griffiths & de Haseth, 2007) is a powerful spectral analysis technique, implemented in the Michelson interferometer setup (Michelson & Morley, 1887).
Fourier Transform Spectroscopy – operation principle, …
Fourier transform spectroscopy is a method where one computes an optical spectrum from raw data by applying a Fourier transform algorithm. The method is applied in various techniques for spectroscopy – most often in the context of infrared spectroscopy.
