摘要

光纤传感器是一种新发展起来的传感技术。文章介绍了基于自发Raman散射的分布式光纤测温系统的应用及其结构设计

并着重分析了在脉冲光作用下系统的测温原理

同时设计了一个新型的基于薄膜滤光片的用于Raman散射的波分复用（WDM）组件。

Abstract

Optical fiber sensor is a newly developed technology. This paper presents

a distributed fiber temperature sensing system based on spontaneous Raman scattering

its applications and configuration design. The principal operation of the system pumped by a pulsed laser is analyzed emphatically. A new type of WDM based on the thin film filters used in Raman scattering is designed.
