分布式传感因其大容量、高空间分辨率和长传感距离的特性被广泛应用于各种传感领域.但高精度传感的需求不断增长,传统的光时域反射计已难以满足空间分辨率的需求,因此,具有更大空间分辨率潜力的光频域反射计越来越受到人们的关注,并且逐渐展现出其在复用光学元件的优势.本文综述了光频域反射计的研究进展,包括发展高空间分辨率和长极限传感距离,介绍了当前基于光频域反射技术的分布式传感应用,总结了光频域反射计复合传感技术,包括与光纤光栅、法布里-珀罗干涉仪以及锥形光纤相结合的复合传感技术,最后对光频域反射计技术做出展望.
Research Progress of Distributed Sensing and Composite Sensing Based on Optical Frequency Domain Reflectometer
Distributed sensing is widely used in various sensing fields because of its characteristics of large capacity,high spatial resolution,and long sensing distance.However,with the growing demand for high-precision sensing,the traditional optical time domain reflectometer is difficult to meet the demand for spatial resolution.Therefore,the optical frequency domain reflectometer with higher spatial resolution potential has attracted more and more attention,and gradually showed its advantages in multiplexing optical components.This paper reviews the research progress of optical frequency domain reflectometer,including the development of high spatial resolution and long limit sensing distance,introduces the current distributed sensing applications based on optical frequency domain reflectometer,and summarizes the composite sensing technology of optical frequency domain reflectometer,including the composite sensing technology combined with fiber grating,Fabry-Perot interferometer,and cone fiber.Finally,the prospect of optical frequency domain reflectometer technology is given.
