DTIC AD0409869: SPECTROSCOPIC STUDIES USING FOURIER TRANSFORMATIONS(RECHERCHES SUR LA SPECTROSCOPIE PAR TRANSFORMATION DE FOURIER)

The use of the Michelson interferometer for spectroscopy in the infrared is considered and the following are discussed: Fourier analysis of the interferogram using high-speed digital computers and analog methods, instrumental errors, analysis of noise and procedures for attaining maximum s/n ratios, specific applications to night sky spectrometry in the micron to 1.6 micron region as well as to the re-emission spectrum of germanium, and comparison of this method with those using classical spectroscopic instruments.
