Abstract : A new type of anemometer based on low coherence interferometry is examined, In the proposed scheme, a fluctuation of an interference output formed with a light component scattered at a chosen depth in a fluid is detected and is fourier-processed. Consequently, a distributed sensing of the flow velocity along the depth can be achieved. (Author)
