Abstract:

Fourier spectroscopy is a technique discovered by Michelson in 1891 that recently began its renaissance with the advent of high-speed digital computers. Examples of results that were obtained with Fourier spectroscopic techniques to measure spectra of the planets in the near-infrared and spectra of gases in the far infrared are shown. The principles of Fourier spectroscopy are explained along with comments on practical techniques. A brief description of the computational techniques are given and a comparison of the advantages and disadvantages of Fourier spectroscopy versus conventional grating spectroscopy is made. The Aerospace Corporations far-infrared, lamellar-grating interferometer is described and some results obtained while using it are shown. The prospects for the future of Fourier spectroscopy are also discussed. Author
