Abstract : An experimental study is reported of temporal disturbances in interferometric spectroscopy. Using a Michelson interferometer, with a sweep length and sweep time of 200 microsec and 0.2 sec respectively, interferometer noise, the false spectra caused by source intensity modulations, and white noise vibrations were studied. Using a wave analyzer reduction of the interferograms and assuming a 90 degree phase difference between the interferometer source frequencies and the modulation frequencies, the false spectra was subtracted from the true spectra. The accuracy of this subtraction was then correlated to a signal to modulation ratio. There is also extensive coverage of the laboratory techniques developed for near infrared measurements in interferometric spectroscopy. (Author)
