  • Laser anemometer
    Patent number: 6847437
    Abstract: The present invention relates to a laser anemometer making it possible to determine the relative velocity between the anemometer and an ambient medium. The architecture of the anemometer includes a laser source, emission and reception optics for focusing a laser beam onto a measurement zone containing particles in suspension in the ambient medium and for receiving the radiation back-scattered by the particles. It also includes an optical mixer for mixing the received radiation and reference radiation representing the radiation emitted by the source, and a detector at the output of the mixer. The relative velocity between the anemometer and the ambient medium is determined by computation on the basis of the Doppler effect generated by the radiation and detected by the detector. The laser source is located remotely from a common support which carries the optical emission and reception system as well as the mixer. It is connected to this common support by at least one optical fiber.
