Abstract
An interference spectrometer which analyzes an unknown light beam for determining the presence and amount of particular frequency by passing the light beam through an interferometer with a moving mirror, which transforms the beam into a first signal which represents the inverse Fourier transform of the electrical light beam. An associated laser beam is also processed by the interferometer and detected to give a second signal. The first signal is sampled at each periodic variation of the second to generate a discrete signal which is then digitized. A digital Fourier series frequency component synthesizer synthesizes preselected discrete frequency components of the incoming beam which correspond, for example, to the gaseous components of interest. A particular gas handling apparatus is disclosed which is adapted to handle unstable inhomogeneous gases such as automobile exhaust fumes.
