摘要
随着对光纤中非线性效应研究的不断深入,光纤分布式传感器得到了广泛的研究和应用.本文介绍了光纤传感的应用领域,综述了基于布里渊散射、拉曼散射及瑞利散射3种散射光实现不同类型光纤分布式传感的原理,最后从光纤分布式传感优势方面对其未来发展方向进行了展望.
With the deepening study of nonlinear effect in optical fiber, the distributed optical fiber sensor has been widely studied and applied. In this paper, the application of optical fiber sensor is introduced. To realize different types of fiber distributed sensing, the principle of three kinds of scattered light based on Brillouin scattering, Raman scattering, and Rayleigh scattering is summarized. Finally, the future development direction of fiber distributed sensing is prospected.
