Abstract

A time domain multiplexed system for strain or temperature monitoring using four Bragg gratings arranged along one fibre is constructed and tested. A Michelson interferometer allows the wavelength shift of the light reflected from a strained or heated fibre grating to be converted into phase information and thus determine the measurand.
