WebJun 30, 2024 · The Bragg wavelengths of the FBGs were recorded every 10 °C. The results are shown in Figure 6. According to the calibration curve, the change in the Bragg wavelength of the sensors had a good linear relationship with the temperature. After linear fitting, the temperature sensitivities of FBG1–FBG9 sensors were, respectively, 10.50 … WebA drawback of the PM technique is that a separate PM is required to obtain FBGs with different Bragg wavelength. However, by stretching or compressing the fibre during inscribing, the Bragg wavelength can be tailored slightly. In addition, chirped FBGs can also be fabricated by the PM technique.
