Abstract
Limitations on the performance and capabilities of conventional fibre optic Doppler Anemometers (FODAs) are highlighted in the context of fluid flow measurement. In order to overcome these difficulties, a novel optical fibre signal processing scheme is outlined, based on a low coherence interferometric approach using an optical delay cavity matched for the position of the required measurement volume. Both a homodyne and a heterodyne system are discussed and experimental results are presented to verify the feasibility of the proposed method.
