A Fourier Transform spectrometer consists of a Michelson interferometer with a moveable mirror and a broadband source. An interference pattern is obtained at each position of the mirror, and these ‘interferograms’ are combined and a Fourier transform calculated to retrieve the absorption at each wavelength. The technique is a rapid and efficient method for measuring the absorption spectra of samples, and can be used for both solid state structures and pharmaceutical samples.
