  • Method of frequency comb generation, associated generation module, remote spectroscopy method and associated spectroscopy device
    Patent number: 11079323
    Abstract: A method of generating frequency combs composed of a predetermined number of rays, wherein the method includes the modulation of a main ray generated by a laser source (20), by a first radiofrequency signal at a first frequency value, by a second radio frequency signal at a second frequency value, and by a third radio frequency signal at a third frequency value. The second frequency value is equal to twice the first frequency value. The third frequency value is equal to three times the first frequency value.
    Type: Grant
    Filed: May 22, 2018
    Date of Patent: August 3, 2021
    Assignees: CENTRE NATIONAL D'ETUDES SPATIALES, OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES
    Inventors: Philippe Hébert, François Lemaître, Xavier Orlik, Thibault Dartigalongue
  • Remote spectroscopy device with a composite laser source and associated remote spectroscopy method
    Patent number: 10466105
    Abstract: Disclosed is a remote spectroscopy device of the LIDAR type including a module for generating an emission signal, an emission module for sending the emission signal toward a targeted material, a receiving module for receiving a response signal and a module for postprocessing of the response signal to determine a composition of the targeted material. The generating module includes at least two laser sources, each laser source being able to generate a laser signal at a predetermined wavelength, an upstream mixer able to mix the laser signals generated by the different laser sources, and a first modulator able to modulate the composite signal at a first modulation frequency to form the emission signal.
