Abstract
Spectral analysis of a beam of radiation is carried out by splitting the beam of radiation into its respective spectral components and by applying a characteristic modulation to each of the spectral components before allowing them to fall on a common detector. The super-imposed signals generated by the detector and representative of the spectral components are then electronically segregated by reference to the characteristic modulations that have been applied to the individual spectral components. This is conveniently done by generating a series of modulated reference signals which have been modulated in exactly the same way as the spectral components of interest. The technique is not restricted to optical spectra but can also be used, for example, for X-ray spectra and mass spectra.
