Abstract

A novel optical fibre fluid velocity sensor is described that is based on a specially manufactured optical fibre fused tapered coupler, folded to produce a 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.
