Patent

CA 2305202

The invention concerns an optical detector comprising a class B laser source (1) emitting a beam (3) at a first optical frequency; means (4) interacting with the beam (3) to supply a radiation (5) at modified optical frequency, the phase shift between the first frequency and the modified frequency being close to the laser relaxation frequency; means (6) for irradiating a selected zone of a medium to be studied by means of radiation at the modified frequency; means (6; 6', 12") for injecting into the laser the light sent back by the selected zone; and means (9, 14, 15, 16) for detecting the disturbance in the laser output brought about by the re-injected light.

L'invention concerne un détecteur optique comprenant une source laser (1) de classe B émettant un faisceau (3) à une première fréquence optique; un moyen (4) interagissant avec le faisceau (3) pour fournir un rayonnement (5) à fréquence optique modifiée, le décalage entre la première fréquence et la fréquence modifiée étant voisin d'une fréquence de relaxation du laser; un moyen (6) pour irradier une zone choisie d'un milieu à étudier par le rayonnement à la fréquence modifiée; un moyen (6; 6', 12'') pour injecter dans le laser de la lumière renvoyée par la zone choisie; et un moyen (9, 14, 15, 16) pour détecter la perturbation apportée à l'émission laser par la lumière réinjectée.
