The principles and practice of astronomical imaging Fourier transform spectroscopy (FTS) at far-infrared wavelengths are described. The Mach–Zehnder (MZ) interferometer design has been widely adopted for current and future imaging FTS instruments; we compare this design with two other common interferometer formats. Examples of three instruments based on the MZ design are presented. The techniques for retrieving astrophysical parameters from the measured spectra are discussed using calibration data obtained with the Herschel–SPIRE instrument. The paper concludes with an example of imaging spectroscopy obtained with the SPIRE FTS instrument.

This paper provides an introduction to Fourier transform spectroscopy. The basic concepts of the Fourier transform technique are reviewed. These include the characteristics and generation of interferograms and the generation of spectra by the Fourier transformation of interferograms. The multiplex and throughput advantages and the data handling disadvantages are also discussed. The optical, electronic, and data-handling instrumentation and techniques necessary for a Fourier transform spectrometer system are, in general, quite different from those of a conventional prism or grating spectrometer. The requirements of these areas are outlined and recent developments are reviewed. The Fourier transform technique has been successfully applied to a number of spectral measurements from the visible through to the far infrared. Some of the more recent applications are discussed.
