Abstract
A fibre optic sensor probe based on the fluorescence quenching of an o ptically active sol-gel coating is demonstrated. The simplified probe design includes a blue LED light source, a photodiode silicon detector and a bifurcated optical fibre. The sensor performance was characteri sed by a detection limit of <1ppm of oxygen vapour, a response time of <10s and a linear dynamic range for oxygen concentrations extending f rom 1 to 1000ppm.
