Fourier Transform Spectrometry in Relation to Other Passive Spectrometers

J. W. Brault


The relative merits of Fourier transform spectrometers and alternative passive spectrometers are explored qualitatively with emphasis on the quantity, quality, and cost of information flow. This includes a brief look at throughput, detector considerations and spectral coverage; resolution and accuracy in intensity and wavelength; and cost of construction and data reduction. Finally, the possibilities of multiple detectors and extensions of the technique to the vacuum ultraviolet by means of all-reflecting wavefront division interferometers are mentioned.
