Patent abstract
A sampling spectrophotometer comprising an interferometer is used for performing a spectral analysis of light produced by a source. The sampling is adapted for eliminating uncertainty in the frequencies that are associated with spectral components deduced from an interferogram. Preferably, the interferometer is of Michelson type, and is equipped with at least one staircase mirror in one of the two optical paths. Elementary reflecting strips of the staircase mirror can then be offset with respect to one another according to a variable step.
