OPTICAL FIBRE GRATING-BASED SENSORS FOR HUMIDITY MEASUREMENT: DESIGN AND APPLICATIONS

L. Alwis, T. Sun, K. T. V. Grattan
Abstract:
This paper presents the results of work done on the development, evaluation and testing of several different designs of fibre optic (FO) grating-based sensors for humidity measurement, evaluated in the laboratory and beyond. The basic operation and design of the sensors is reported, as is a comparison of the use of both optical Fibre Bragg Grating (FBG) and Long Period Grating (LPG) systems as the basis of an effective sensor device. Applications of sensors of this type are discussed as is the tailoring of the devices to specific requirements for industrial measurements.
