光纤倏逝场传感器对甲醇 （CH3OH）和乙醇（C2H5OH）基于变形光学溶剂 纤维芯的报道。现有的U型的敏感性 探讨提高延长暴露芯线圈形状 一个半圈的形成，核心行进 三弯曲的形状。利用可见光的波长区域（VIS） 甲醇/乙醇从0 到10 所示的浓度 的弯曲形状的传感器使测定灵敏度 更好的甲醇浓度比0点05 和 乙醇的浓度比0 在650nm。这有利于 低成本的光源和接收器使用规定 这个波长范围以及聚合物的光的利用 纤维导光和从传感器，从而导致较低的 成本的应用相比，所有的二氧化硅或聚合物包层石英光纤 在近红外（NIR）解决方案或紫外线（UV）波长 范围。 (An optical fibre evanescent field sensor for methanol (CH3OH) and ethanol (C2H5OH) solvents based on deformed optical fibre cores is reported. The sensitivity of an existing U-bend probe is increased by extending the exposed core to a coil shape of one and a half turns and by forming the core to a meander shape with three bends. Using the visible wavelength area (VIS) and methanol/ethanol concentrations from 0 to 10 it is shown that the sensitivity of the meander shape sensor enables the determination of methanol concentrations of better than 0:5 and of ethanol concentrations of better than 0:2 at 650nm. This facilitates the use of low cost optical sources and receivers provided for this wavelength range as well as the utilization of polymer optical fibres to guide the light to and from the sensor which results in low cost applications compared to all silica or polymer clad silica fibre solutions in the near-infrared (NIR) or ultra-violet (UV) wavelength range.)
