A Spectrometer System and a Method for Compensating for Time Periodic Perturbations of an Interferogram generated by the Spectrometer System A spectrometer system (2) comprises a scanning interferometer (4); a drive system (6) mechanically coupled to a movable reflector element (14) of the scanning interferometer (4) and operable to effect reciprocation of the movable reflector element (14)at a plurality, preferably more than two, for example three, different scan speeds; a detector arrangement (8) configured to sample at equidistant time intervals an interferogram formed by the scanning interferometer (2) to generate a sampled interferogram; and a data processor (10) is adapted to acquire a sampled interferogram at each of the plurality of different scan speeds and to perform a relative comparison of the content of the so acquired plurality of sampled interferograms. |
