摘要

Abstract

An optimized single-end hybrid Rayleigh

Brillouin

and Raman distributed fiber sensing system has been developed for simultaneous measurement of multiple parameters. This system integrates 3-bit pulse coding for the Raman signal and the Brillouin amplification of the Rayleigh-backscattered signal

discriminating strain

temperature

and vibration using a single sensing fiber.
