Une nouvelle méthode de détection pour mesurer directement la vitesse d'écoulement en utilisant des techniques d'interférence à faible cohérence est proposée et démontrée. Dans cette méthode, un signal fluctuant dans le temps, et non le décalage de fréquence Doppler, est détecté. L'analyse théorique montre qu'un spectre de lumière rétrodiffusée par une particule prend une forme gaussienne dont la largeur est simplement proportionnelle à la vitesse d'écoulement. La vitesse mesurée est en bon accord avec la vitesse d'écoulement réelle dérivée du débit. La plage dynamique de cette méthode de détection est régie par la plage de fréquences du processeur FFT utilisé et est estimée à 1.4.

Abstract: A new sensing method for measuring directly flow velocity by using low coherence interference techniques is proposed and demonstrated. In this method, a temporally fluctuating signal, not the Doppler frequency shift, is detected. Theoretical analysis shows that a spectrum of light backscattered from a particle takes a Gaussian form whose width is simply proportional to the flow velocity. The measured velocity is in good agreement with the actual flow velocity derived from the flow rate. The dynamic range of this sensing method is governed by the frequency range of the FFT processor used and is estimated to be 1.4
