Abstract
An instrument for determining spectral content of an input light. The instrument has a rotating optical element that separates an input light into two partial beams and thereby introduces a variable OPD between the partial beams. The instrument then records an interferogram as a function of the variable OPD and thereby Fourier or Fast Fourier transforms the interferogram into a spectrogram so that the spectral content of the input light is revealed.
