A novel optical fibre fluid velocity sensor is based on a specially manufactured fused optical fibre tapered coupler, folded to produce probe geometry. The splitting ratio of this miniature transducer is sensitive to bending and can be easily and cheaply measured using an LED source and simple opto-electronics. The packaging of the transducer has been optimised to produce a sensor for fluid velocity measurements. A description of the fabrication process and the results obtained during initial airflow measurements in a wind tunnel are presented.
