The article focuses on the Fourier-transform spectroscopy (FTS), a well-established spectroscopic method, that is used to improve and complement the performance of grating or prism spectrometers. The method is applicable for the measurement of the speed of light, for the definition of the meter and wavelength standard and for the development of accurate reference spectra. Morever, FTS instruments are also applicable in various industrial applications because of their rapidity and simplicity.
