Abstract: The spectrometry apparatus of the present invention includes, in addition to conventional analysis, a first diaphragm having a first chosen variable aperture for spatially filtering a coherent-excitation beam. The apparatus also includes a first deflector stage (DF1) for sweeping an excitation beam over a sample according to a first chosen deflection. Additionally, there is included a second diaphragm having a second variable aperture conjugate with the first aperture for filtering the incoherent-scattering beam. The spectrometry apparatus further provides a second deflector stage placed downstream in order to sweep the spectral image of the incoherent-scattering beam thus filtered over the multichannel detection module according to a second chosen deflection.

Abstract: The invention relates to a method of discrimination in spectrometry, particularly of eliminating phenomena of fluorescence in Raman spectrometry. According to the invention, a sample (6) is excited by a luminous pulse (5) generated from a laser (1). The light (7) emitted by the sample (6) is directed into an interferometer (8) of which the duration of a round trip of a luminous ray is significantly longer than the duration of the pulse of the incident wave and shorter than the duration of the phenomenon of fluorescence. The resulting light (9) is then directed to a second interferometer (10) of which the optical path is slightly different from that of the preceding interferometer (8). The light (11) is recovered at the outlet of the second interferometer (10) and this wave is analyzed by means of a spectrometer (12). The invention is applicable particularly to the analyzing of samples in the chemical industry.
