Abstract[English]
Method and apparatuses are provided for determining gas sample concentration by exciting molecules of a gas sample with an excitation laser and applying a probe modulation signal to a probe laser. The probe laser's output is split into a reference beam and a test beam, with the test beam passed through the sample reservoir, then the reference beam and test beam are recombined to create a signal representing relative phase shift variations between the test beam and the reference beam. This signal is detected and processed to determine gas sample concentration data.[French]
L'invention concerne un procédé et des appareils pour déterminer une concentration d'échantillon de gaz par excitation de molécules d'un échantillon de gaz avec un laser d'excitation et application d'un signal de modulation de sonde à une sonde à laser. La sortie de la sonde à laser est divisée en un faisceau de référence et un faisceau de test, le faisceau de test traversant le réservoir d'échantillon, puis le faisceau de référence et le faisceau de test sont recombinés pour créer un signal représentant des variations de déphasage relatif entre ceux-ci. Ce signal est détecté et traité pour déterminer des données de concentration d'échantillon de gaz.
