Distributed Fiber Voice Sensor Based on Phase-Sensitive Optical Time-Domain Reflectometry
A fiber-optic phase-sensitive optical time-domain reflectometry ('-OTDR) distributed sensing system has been proposed and demonstrated for human-voice detecting and reproducing applications. The fiber strain induced by the voice is ultra small (just a few n"); thus, the change of related R...
