Amplified OTDR Systems for Multipoint Corrosion Monitoring

Amplified OTDR Systems for Multipoint Corrosion Monitoring

We present two configurations of an amplified fiber-optic-based corrosion sensor using the optical time domain reflectometry (OTDR) technique as the interrogation method. The sensor system is multipoint, self-referenced, has no moving parts and can measure the corrosion rate several kilometers away...
