  • Coherent periodically pulsed radiation spectrometer
    Patent number: 5748309
    Abstract: A spectroscopy method is defined in which a first source of radiation (51) emits a periodically pulsed beam (A) having a repetition frequency .omega. and in that a second source of radiation (52) emits a periodically pulsed beam (B) having a repetition frequency .omega.+.DELTA., the beams are united with each other and directed at a material specimen (6) to be analyzed and a detector means determines the amplitudes of the frequency components n.DELTA. of the beam emanating from the material specimen.
