Abstract

A D-fiber evanescent field methane sensor has been reported by Culshaw et al., where a sinusoidally modulated Fabry-Perot interferometer was used for signal processing. To optimize the sensitivity, it is essential to establish a relation between output signal, methane concentration, and certain other key parameters. Previous work with open-path cells, which use a sawtooth driven Fabry-Perot interferometer, shows a noise-limited detection level of ± 0.003% methane (1s time constant). However, no analytic expression has been reported to relate the key parameters in the system. In this paper, we report such a relation and calculate the optimal values of some key parameters.
