The far infrared region has benefited considerably from the introduction of Fourier Spectroscopy, a topic of which the generalities have now been treated by a number of authors. Basically its advantages come from the ability of a two beam interferometer like Michelson’s to pass a greater amount of information than any other “delay” instrument for a given size and spectral resolution. (1) This is of great importance in a spectral region where source brightness is low. It does, however, demand the additional process of Fourier Transformation to give spectra, but modern digital computers can do this very economically and rapidly to any required resolution.
