Abstract (EN): A novel interrogation technique for multiplexing LPG-fiber loop mirrors has been proposed and experimentally demonstrated. Each displacement sensor is formed by a fiber loop mirror combined with a long period grating. This high reflectivity variable mirror is suitable to be interrogated by an OTDR and to be multiplexed in a crosstalk free setup with temperature independence.
