摘要

前向布里渊散射光纤传感器可以检测和分析标准光纤包层外导光无法到达的介质。迄今为止,几乎所有此类传感器都依赖于光纤的径向对称引导声模式。这些模式下的波动是严格的膨胀。然而,前向布里渊散射也通过光纤的扭转-径向引导声模式发生。扭转-径向模态表现出更复杂的张量特征,它们由膨胀波和横波贡献组成。在这项工作中,我们证明了通过扭转-径向声学模式的前向布里渊传感与基于径向声学模式的过程在本质上是不同的。虽然膨胀波分量可能向光纤包层外的液体消散,但剪切波不会。因此,外部液体的影响在扭转-径向模式之间是不同的。那些由膨胀分量主导的模态衰减速度更快,而在相同的液体中,其他具有大剪切贡献的模态衰减速度要慢得多。衰减率的差异可能达到7倍。分析结果很好地支持了实验观察结果。在特定涂层外的液体中也发现了模式之间的差异。当固液相变发生在包层边界外时,衰减率发生较大变化。对多模式类别的监测提供了对外界介质更完整的评估,提高了前向布里渊散射光纤传感器的能力。

Tensor characteristics of forward Brillouin sensors in bare and coated fibers
Forward Brillouin scattering fiber sensors can detect and analyze media outside the cladding of standard fibers, where guided light does not reach. Nearly all such sensors reported to-date have relied on the radially symmetric guided acoustic modes of the fiber. Wave motion in these modes is strictly dilatational. However, forward Brillouin scattering also takes place through torsional–radial guided acoustic modes of the fiber. Torsional–radial modes exhibit more complex tensor characteristics, and they consist of both dilatational and shear wave contributions. In this work, we show that forward Brillouin sensing through torsional–radial acoustic modes is qualitatively different from processes based on the radial ones. While dilatational wave components may dissipate toward liquids outside the fiber cladding, shear waves do not. Consequently, the effect of outside liquids varies among torsional–radial modes. Those modes that are dominated by their dilatational components undergo faster decay rates, whereas other modes with large shear contributions decay at much slower rates in the same liquid. The difference in decay rates may reach a factor of seven. Experimental observations are well supported by the analysis. The differences among modes are also found with liquid outside specific coating layers. Large changes in decay rates are observed when a phase transition between solid and liquid occurs outside the cladding boundary. The monitoring of multiple mode categories provides more complete assessment of outside media and enhances the capabilities of forward Brillouin scattering fiber sensors.
