A Simple Method for Enhancing the SNR in Direct Detection (p-OTDR based Distributed Acoustic Sensors
(IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2020)
A simple and effective method for increasing the SNR and range in fp-OTDR based direct -detection distributed acoustic sensors is proposed and experimentally verified. The proposed method results in 11 dB SNR improvement ...
Performance Analysis of Specialty Fiber Optic Cables for Distributed Acoustic Sensing
(Optica Publishing Group (formerly OSA), 2020)
In this work, we present the signal-to-noise ratio comparison results of six different buried fiber optic cable for identical external perturbations using a home-made direct detection φ-OTDR system.
Experimental Analysis of Non-linear Phenomena due to Perturbation Amplitude in φ-OTDR Based Fiber Optic Distributed Vibration Sensor
(Optica Publishing Group (formerly OSA), 2020)
We experimentally analyze the non-linearity effect due to the perturbation amplitude in the φ-OTDR based fiber optic distributed vibration sensor by investigating the effects of large disturbance signal.
