Acoustic Emission-Based Leakage Detection System Using Coherent Optical Time Domain Reflectometry (COTDR)

摘要

In this paper, we discuss an approach for accurate estimation of position and dimensions of cracks on pipes with flow. Analytical calculations are performed to find the dimensions of cracks using acoustic spectral signatures which are generated due to leaks. Simulations are carried out for Phase-OTDR using coherent Rayleigh scattering.
