Analysis of distributed optical fibre acoustic sensors through numerical modelling
Distributed optical fibre dynamic strain sensor is numerically modeled. To increase the flexibility of the model, the building blocks of the sensing system are modeled separately and later combined to form the numerical model. This approach is adopted to facilitate the evaluation of each building block and their effect on the output of the sensor. The numerical model is used to assess the effect of parameters such as the linewidth of the laser source, the width of the probe pulse, and the frequency and amplitude of perturbation on the response of the sensing system. It is shown that the precision and accuracy of the sensing system are affected by the frequency and amplitude of perturbation as well as the pulse width and linewidth of the probe pulse.

Abstract
Distributed optical fibre dynamic strain sensor is numerically modeled. To increase the flexibility of the model, the building blocks of the sensing system are modeled separately and later combined to form the numerical model. This approach is adopted to facilitate the evaluation of each building block and their effect on the output of the sensor. The numerical model is used to assess the effect of parameters such as the linewidth of the laser source, the width of the probe pulse, and the frequency and amplitude of perturbation on the response of the sensing system. It is shown that the precision and accuracy of the sensing system are affected by the frequency and amplitude of perturbation as well as the pulse width and linewidth of the probe pulse.
