High-resolution Photon Counting OTDR based Interrogation of Multiplexing Broadband FBG Sensors
… optical time domain reflectometry (pc-OTDR) based multiplexing technology. The system uses a Fresnel reflection OTDR with a zero deadzone to detect FBG sensors, which improves both the system detection ability and spatial resolution. A low reflectance FBG with broad bandwidth has …
