  • Publication number: 20120186337
    Abstract: A device for characterizing the nature of an aerodynamic stream along a wall, the device including multiple temperature-sensitive optical nodes of Bragg grating type distributed along an optical fiber, and means for determining the variations in speed of the aerodynamic stream. The nodes are distributed along a fiber placed substantially following the route of a streamline, and processing means are devised so as to differentiate the temporal and spatial characteristics of the signals of thermal flowrate among the nodes.

  • Patent number: 7982863
    Abstract: The subject of the present invention is a laser anemometry probe for optical homodyne detection of frequency offset by Doppler effect, comprising two devices (DERF1, DERF2) for transmitting/receiving beams in two different directions, avoiding duplicating a plurality of elements of a mono-axial laser anemometry probe.

  • Publication number: 20110141471
    Abstract: An optical anemometric probe includes a laser source emitting a linearly polarized primary light beam and an optical block having splitting means for separating the primary beam, an optical reference pathway, an optical emission pathway and an optical measurement pathway. The optical block includes optical means of rotation of the polarization arranged at the output of the laser source and before the splitting means. The optical emission pathway has an optical circulator, a first optical emission/reception head illuminating a first measurement zone, and a second optical emission/reception head illuminating a second measurement zone. The optical circulator has four ports, e.g., a first input port, a second and a third input/ouput port linked respectively to the first optical head and to the second optical head, and a fourth port linked to the optical measurement pathway.
