Paper Abstract

Results of the characterisation of a quasi-distributed optical fibre chemical sensor are presented. Sensors have sections of cladding containing immobilised chemically sensitive compounds. Optical time domain reflectometry technique is used for sensor interrogation exploiting evanescent wave interactions. Responses of Cresol Red and cryptocyanine dye based sensors to alkaline and acid vapours are presented and discussed.
