Pump encoding in distributed Brillouin fiber sensors

Abstract:

Pump encoding is an effective approach to enhance the weak signal detection in distributed Brillouin fiber sensors.In this paper,a new encoding matrix that can improve the detection performance is proposed.Furthermore,a distributed fiber sensor for both single and encoding pump operations is numerically analyzed by using Brillouin-scattering coupled amplitudes equations.The results demonstrate that the matrix can reduce the transmission times for pumping light and simplify the coding process.The power of th...
