Abstract
We model interference effects in a D-fibre evanescent wave methane sensor and predict its influence on the performance of the system. System sensitivity in terms of minimum detectable methane concentration is expressed as a function of birefringence and spectral transmission characteristics of the D-fibre, polarisation dependent loss occurring after the sensing D-fibre, and polarisation and coherence characteristics of the light source. The sensitivity is calculated for various system arrangements and is found to agree with experimental results.
