Abstract

A flow sensor is presented based on the deflection of a 1 mm diameter grooved polymer optical fibre in an air flow. By measurement of optical strain in two orthogonal directions, the sensoris able to measure both the magnitude and direction of air velocity, by performing vectorial addition of the flow componentisn two orthogonal directions. Experiments in a wind tunnel showed that the sensor was unaffected by its orientation o the flow. It is able to measure very a flow range of 0 to 35 m/s, with a sensitivity of 0.0049f 0.001u nits of optical strain s/m and a resolution of 0.844 m/s.
