“…Each position of the moving mirror gives a phase relationship between the two partial beams. After recombination of the component beams the modulation of intensity caused by the position change depending on time can be transformed by Fourier analysis to spectral information (wavenumber) [69][70][71][72]. Although modern computers calculate such spectra in fractions of a second, they can give high resolution only if the moving mirror is positioned exactly by using laser interference (Dx % 1/Dl).…”
