Noise model of the scale limitation in TDM interferometric fiber-optic sensor system

Abstract

In this paper, we build a noise model to investigate the number of sensors in fiber-optic interferometric sensing TDM system. The noise model incorporates many parameters which may have an effect on the number of sensors in the system, such as the various key noise and the optical power. Utilizing the noise model, we get the characteristics of system noise and major noise contributions under different numbers of sensors by simulation. The noise model we build can offer guidelines for the design of the interferometric fiber-optic sensing TDM system.
