• The Development of an $\Phi $ -OTDR System for Quantitative Vibration Measurement (2015, background): “PHASE-SENSITIVE optical time-domain reflectometry ( -OTDR) is a powerful technique that allows fully distributed vibration sensing with fast response and high sensitivity, which has been applied in many fields such as civil structure health monitoring and security guarding [1]–[3].”
• Phase-sensitive Optical Time Domain Reflectometer Assisted by First-order Raman Amplification for Distributed Vibration Sensing Over >100 km (2014, methodology): “In addition, a semiconductor optical amplifier (SOA) and an optical switch are used to gate the φOTDR pulses, achieving a strong reduction of the coherent in-band noise [5].”
