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-,
infrared- (
FTIR), nuclear magnetic
resonance-, and electron spin-
resonance spectroscopy. There are several methods for measuring the temporal coherence of the light, including the
CW Michelson or
Fourier-transform spectrometer and the pulsed Fourier-transform
spectrograph (which is more sensitive and has a much shorter sampling time than conventional spectroscopic techniques).
