Abstract
A simple and effective modeling methodology for simultaneous measurement of strain and temperature using fiber Bragg grating is described. The performance of the FBG based sensor is studied utilising the optical delay line signal processing technique in Z-domain. The sensor works by detecting the shift in the resonant mode in the reflection spectrum. When the grating is subjected to temperature and strain variations, the optical path lengths change, resulting in this shift.
