  • Abstract : This research activity focuses on the implementation of interrogation techniques to demodulate distributed or quasi-distributed physical optical fibre sensors.
  • Description : - Use of a commercially available (photon-counting-) optical time domain reflectometer and some passive components to interrogate identical low reflective fibre Bragg gratings cascaded along a single optical fibre; - Implementation of a coherent optical time domain reflectometer technique for quasi-distributed temperature and strain measurements; - Vibration measurements through polarization related phenomena measurements.
  • Applications : - Temperature measurements - Strain measurements - Intrusion detection - Vibration sensing
