Abstract
A spectrometer is provided, the spectrometer having an interferometer generating an interferogram by splitting an interferometer input signal between a reference arm and a variable delay arm, and introducing a delay between the split interferometer input signals prior to interfering the split interferometer input signals. The spectrometer additionally has a controllable delay element operable to adjust the delay introduced by the interferometer and a dispersive element outputting a plurality of narrowband outputs representative of a received broadband input signal. The interferometer and dispersive element are optically connected to output a plurality of narrowband interferograms representative of a spectra of a spectrometer input signal received by the spectrometer, and the plurality of narrowband interferograms are received by a detector array for analysis.
