Fourier-transform spectroscopy

https://doi.org/10.1351/goldbook.FT07382
Measurement technique whereby spectra are collected based on measurements of the temporal coherence of a radiative source, using time-domain measurements of the electromagnetic radiation or other type of radiation.
Note:
This procedure can be applied to a variety of spectroscopies including optical-, @[email protected] (FTIR), nuclear magnetic @[email protected], and electron [email protected]@ @[email protected] There are several methods for measuring the temporal coherence of the light, including the CW Michelson or @[email protected] and the pulsed Fourier-transform @[email protected] (which is more sensitive and has a much shorter sampling time than conventional spectroscopic techniques).
