Abstract
The principles and application of heterodyne techniques to optical and infrared spectroscopy are discussed. Examples are drawn from the field of atomic isotope shifts and hyperfine structure and from molecular spectroscopy. Measurement of beat frequencies between two laser beams is considered, but also the detection of incoherent radiation by employing a laser local oscillator is reviewed. Applications in astronomy provide examples of the latter technique.
