Self-Referenced Spectrometer


Aspects of the present disclosure relate to a self-referencing spectrometer for providing simultaneous measurement of background or reference spectral density and sample or other spectral density. The self-referencing spectrometer includes an interferometer optically coupled to receive an input beam and to direct the input beam along a first optical path to produce a first interference beam and to direct the input beam along a second optical path to produce a second interference beam, wherein each interference beam is produced prior to an output of the interferometer. The spectrometer also includes a detector optically coupled to simultaneously detect a first interference signal generated from the first interference beam and a second interference signal generated from the second interference beam, and a processor configured to process the first interference signal and the second interference signal and to use the second interference signal as a reference signal when processing the first interference signal.
