낮은 간섭 간섭 기술을 사용하여 유속을 직접 측정하는 새로운 감지 방법이 제안되고 시연됩니다. 이 방법에서는 도플러 주파수 편이가 아닌 시간적으로 변동하는 신호를 감지합니다. 이론적 분석에 따르면 입자에서 후방 산란된 빛의 스펙트럼은 폭이 유속에만 비례하는 가우스 형태를 취합니다. 측정된 속도는 유량에서 파생된 실제 유속과 잘 일치합니다. 이 감지 방법의 동적 범위는 사용된 FFT 프로세서의 주파수 범위에 따라 결정되며 1.4로 추정됩니다.

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
