Preferred Label : multiplex spectrometer;
IUPAC acronym : FTS;
IUPAC definition : A spectrometer in which a single photodetector simultaneously receives signals from
different spectral bands which are specifically encoded. In the case of frequency
multiplexing, each spectral band is modulated at a specific frequency. Decoding is
achieved by filtering out, by electronic means, the corresponding signals. Frequency
multiplexing may be realized by changing the path difference between the two interfering
beams at a uniform rate. Fourier transform of the interferogram so obtained yields
the spectrum. This method is called Fourier transform spectrometry (FTS).;
