Performance And Limitations Of Reflectometric Fibre Optical Sensors For Voc Sensing Applications

Interferometric optical sensors are known for the exact determination of path lengths. Equipped with appropriate sensitive polymer coatings, this effect can be used to monitor changes in VOC concentration in vapour phase and water. The performance and limitations of a fibre optical RUS-transducer are reported here with respect to optical components, temperature variation and properties of the polymer coating.
