提出了一种铝嵌入式光纤布拉格光栅（FBG）传感器结构，用于温度和应变的解耦测量。这种配置包括一个三点再生FBG（RFBG）传感器阵列，在一根光纤中的距离为8 mm。一个RFBG与铝直接接触，而其他RFBG通过钢毛细管保护免受铝的影响。与铝接触的RFBG受温度和应变的影响，而其他RFBG仅受温度的影响。这里使用的铸造模具具有第二对称臂，其用于在一个毛细管中具有三个RFBG的附加温度参考测量。两个铸造实验与这种配置，并去耦的温度和应变测量的基础上，一个传感光纤进行了演示。应变传感光纤中的温度值与第二铸造臂中的参考温度显示出良好的一致性。因此，可以证明一根光纤足以同时测量温度和应变，并且应变传感器的温度补偿是成功的。这是迈向智能投顾应用的重要一步。
An aluminum embedded fiber Bragg grating (FBG) sensor configuration for a decoupled temperature and strain measurement was proposed and demonstrated. This configuration consists of a three-point regenerated FBG (RFBG) sensor array with a distance of 8 mm in one fiber. One RFBG was in direct contact with the aluminum, whereas the other RFBGs were protected from the aluminum by a steel capillary. The RFBG in contact with the aluminum was influenced by temperature and strain, and the other RFBGs only by temperature. The casting mold used here had a second symmetric arm used for an additional temperature reference measurement with three RFBGs in one capillary. Two casting experiments with this configuration were made, and decoupled temperature and strain measurements based on one sensing fiber were demonstrated. The temperature values in the strain sensing fiber showed good agreement with the reference temperatures in the second casting arm. Thereby, it could be demonstrated that one fiber was sufficient for both temperature and strain measurement and that the temperature compensation for the strain sensor was successful. This is a significant step towards the application of smart casts.
