Paper Abstract

Dual-channel fiber ring down force sensor based on the principle of time division multiplexing is descried. The system has the capability to interrogate more than two micro bend sensors by using more than one fiber delay line to control the time of flight of the pulse. The dual-channel fiber ring down force sensor with one fiber delay coil is demonstrated with high force sensitivities of 183.4ns/N and 163.6ns/N, respectively. Our system has also good linear responses.
