  • Patent number: 8917396
    Abstract: An embodiment relates to a Fourier transform spectrometer comprising: a coherent light source; an interferometer adapted to separate the coherent light source into two or more parts in order to generate through frequency or phase-induced effects, interferences between the two or more parts; detection means adapted to detect the interferences, wherein the coherent light source comprises a frequency comb generator having a frequency repetition rate, and the detection means are adapted to detect the beating of pairs of frequencies of the frequency comb separated by the frequency repetition rate or a multiple of the frequency repetition rate.
    Type: Grant

    Date of Patent: December 23, 2014
    Assignees: Centre National de la Recherche Scientifique—CNRS, Universite Paris-Sud 11
    Inventors: Nathalie Picqué, Guy Guelachvili, Julien Mandon
  • Publication number: 20110267625
    Abstract: An embodiment relates to an interferometer comprising: a first frequency comb; a second frequency comb adapted to interact with the first frequency comb in order to produce interferences; means for isolating the beating signal between a subset of frequency components among the frequency components of the two combs. This subset of frequency components may be preferably, but not necessarily, a single line of the first frequency comb and a single line of the second frequency comb; means for monitoring this beating signal and using it as a trigger or as a clock for the acquisition unit device recording the beating interference signal between the entire frequency components of the first and the second frequency combs.
