INTERROGATION SYSTEMS FOR MULTIPLEXED FIBER BRAGG SENSORS
Journal Title: Informatyka Automatyka Pomiary w Gospodarce i Ochronie Środowiska - Year 2015, Vol 5, Issue 4
Abstract
Fibre Bragg grating (FBG) sensors have emerged as a reliable, non-destructive tool for monitoring, diagnostics and conrol in many structures. The versality of FBG sensors represent a main advantage over other technologies in the structural sensing field. Mounting many fiber Bragg gratings with different central wavelengths on single fiber creates capacities for building arrays of distributed sensors thus it is possible to determine the magnitudeof the measured value and a spatial location of the measurand change. The interrogation units are responsible for reading the Bragg wavelength shiftof the FBGs induced by various physical parameters like strain, temperature, etc. This research can provide useful information for practical applications
