Abstract

A novel combined fiber Bragg grating (FBG) and interferometric based sensor is proposed and demonstrated. The sensor is based on two overlapped Michelson interferometers working at different wavelengths in a Sagnac loop and two FBGs used as wavelength selective mirrors. The advantage of the system is that it combines the benefit of point measurement with FBG and the high sensitivity of long gauge interferometric sensor.
