Abstract

A cascading distributed fiber Raman temperature measuring system comprises a broadband light source, a bidirectional three-channel fiber coupler, a single-mode fiber, an optical relay amplifier, an optical splitter, a first photoelectric receiver, a second photoelectric receiver, a signal acquisition card and a computer. The cascading distributed fiber Raman temperature measuring system is mainly used for measuring temperature of power transmission and distribution systems, oil well exploration, gas pipeline systems and the like, and can adapt to various measurement environments by adjustment as required during use. The cascading distributed fiber Raman temperature measuring system has the advantages of safety, reliability, high weather resistance, wide application range, long transmission distance and high electromagnetic resistance.

Description

technical field [0001] The invention belongs to the technical field of optical fiber measurement, in particular to a cascadable distributed optical fiber Raman temperature measurement system. Background technique [0002] In 1870, British physicist Tyndall did a simple experiment: drill a hole in a wooden barrel filled with water, and use a lamp to illuminate the water from the top of the barrel. As a result, the glowing water flowed out of the small hole in the bucket, the water was bent, and the light was also bent. Later, people made a kind of glass fiber with high transparency and very thin. When light hits the glass fiber at a suitable angle, the light will advance along the curved glass fiber. Because this fiber can be used to transmit light, it is called an optical fiber. [0003] Since the 1990s, the photonic industry driven by optical communication has achieved great success. Optical fiber sensors have developed industrially and have a wide range of applications, ...
